Welcome to Hotspur Way, where Micky van de Ven will be sitting alongside Igor Tudor taking questions from the media ahead of tomorrow's match with Atletico Madrid.
The centre-half has been criticised by Tottenham fans of late for his performances and the red card versus Crystal Palace in the Premier League.
As one of Tottenham's senior players, it will be interesting to hear his thoughts on the club's season and the lingering threat of relegation.
Some good news for Igor Tudor with Cristian Romero, Lucas Bergvall and Destiny Udogie returning to training this morning.
However, Sunday's goalscorer Richarlison will miss tomorrow's match through suspension.
Poll: Greatest Champions League comeback by an English side?
This may be against the rules as a football supporter, but I find it's hard not to get carried away even when watching one of your domestic rivals complete a dramatic comeback on a big European night.
There is a poll at the top of this page to stir up some of those memories.
Which is your favourite?
Ready for Tottenham's 'La Remontada' - part II?
Tottenham v Atletico Madrid (Wed, 20:00 GMT)
Tottenham Hotspur
Spurs were three goals down on aggregate with 45 minutes remaining of their 2019 Champions League semi-final at Ajax - yet a Lucas Moura hat-trick secured their place in the final on the away goals rule.
That same year, Liverpool suffered a 3-0 defeat in the first leg of their last-four encounter at Barcelona, but won 4-0 at Anfield to make it through.
And Barca themselves overturned a four-goal loss in the first leg of their 2017 last-16 tie against Paris St-Germain to win through 6-5 on aggregate.
That match has become known as La Remontada (The Comeback).
Atletico Madrid also have recent history in this regard - last month they beat Barca 4-0 at home in the first match of a two-legged Copa del Rey tie, but were given an almighty scare in the away leg before eventually making it through 4-3 on aggregate.
So there is hope.

Spurs will have to beat the odds - as well as Atletico
Tottenham v Atletico Madrid (Wed, 20:00 GMT)
Tottenham Hotspur
Whichever Tottenham players are fit enough to take to the field at home to Atletico on Wednesday night, they will face a Herculean task.
Opta's supercomputer has given Spurs a 4.1% chance of reaching the quarter-finals.
They have not won in their past eight matches in all competitions, and failed to win their last four matches at home.
Tottenham's last home win was against Borussia Dortmund on 20 January.
As mentioned, only four teams in Champions League history have overturned a three-goal first-leg deficit to make it through a knockout tie.
But stranger things have happened...
What are the Champions League concussion rules?
Just to reiterate, in the Premier League, any player who has suffered concussion must not return to first team action until they have completed a set process - hence why Spurs' Cristian Romero and Joao Palhinha missed the draw at Liverpool.
But in the Champions League, the onus is on the club to decide - so if Spurs judge Romero and Palhinha to be fit, they can play tomorrow night.
The presence of Romero in first-team training indicates he could be involved, while we wait and see on Palhinha.
Romero with full squad but Pahlinha trains alone

Tottenham Hotspur
The Tottenham first team trained this morning, and there were a couple of positive signs for Spurs fans.
Cristian Romero was with the main training group after missing the weekend draw at Liverpool with concussion, raising hopes the captain could return tomorrow.
As mentioned, Romero clashed heads with team-mate Joao Palhinha against Atletico Madrid - and the on-loan Bayern Munich midfielder was reportedly training alone, so may not be available for the second leg.
Lucas Bergvall and Destiny Udogie, who have both been injury absences, were also in first-team training - but there was no Conor Gallagher, who has been ill.
Richarlison, who scored the late equaliser against Liverpool, was also reportedly training in the gym rather than with the rest of the first team.
What are the concussion protocols?

Ask Me Anything
In the Premier League, if a player is judged to be concussed they must not return to activity for at least 24 hours.
They will then begin a six-stage 'return to play' process, which starts with an initial 48-hour period of rest.
The FA then recommends "a staged and graduated return to full daily activities".
There is no specific time period enforced, it is up to the clubs and their medical departments to judge when each player is fit and ready to play, based on their diagnosis.
Uefa has its own policies, based on a "Recognise, Report and Remove" principle, which again puts the final decision on a player's fitness firmly in the hands of the club's team doctor.

From bad, to worse, to even worse - will Romero & Palhinha be available?
Tottenham v Atletico Madrid (Wed, 20:00 GMT)
Tottenham Hotspur
Just when Igor Tudor was thinking Tottenham's night at the Metropolitano could not get any worse, two of his key players - central defender Cristian Romero and midfielder Joao Palhinha - went for the same ball in stoppage time and suffered a sickening clash of heads.
It was later confirmed they would be unavailable for Spurs' next match - last Sunday's Premier League game at Liverpool - as the club was following concussion protocols.
Their absence added to Tottenham's lengthy injury list, with 13 first-team players missing the trip to Anfield.
The question is - have they recovered sufficiently to be available for selection for Wednesday's return leg?
Spurs reach new low at Atletico
Tottenham v Atletico Madrid (Wed, 20:00 GMT)
Tottenham Hotspur
There was already a question mark over Igor Tudor's appointment as interim manager when Tottenham travelled to Madrid last week for the first leg of their last-16 Champions League tie against Atletico.
Spurs arrived at the Metropolitano Stadium on the back of three consecutive defeats under Tudor, but things went from bad to worse as they conceded four goals in the opening 22 minutes against Diego Simeone's streetwise side.
Tudor made the shock decision to start with 22-year-old reserve goalkeeper Antonin Kinsky, but substituted him after just 17 minutes, reverting back to number one Guglielmo Vicario.
After conceding a fourth goal moments after Vicario's introduction, Tottenham did manage to stem the tide somewhat, with a goal in each half from Pedro Porro and Dominic Solanke, either side of a fifth for Atletico from former Manchester City forward Julian Alvarez.
So Atletico will take to the field in Tottenham on Wednesday with a three-goal cushion.
Only four teams in 51 attempts have managed to come back from three goals down after the first leg of a Champions League knockout tie - could Spurs be the fifth?
Epic comeback anyone?
Champions League
Ready for action?
A huge night of Champions League football awaits.
Manchester City and Chelsea must overcome three-goal deficits if they are to reach the quarter-finals later tonight, while Premier League leaders Arsenal must find a way past a stubborn Bayer Leverkusen side.
But that is for later, today we will be building up to tomorrow's ties, with news conferences to come from the Liverpool and Newcastle camps from 15:30 GMT.
Our first stop, however, is at Tottenham, where interim manager Igor Tudor is busy planning an epic comeback of his own...
