Mathys Tel put in a star performance as Tottenham Hotspur defeated Chelsea last time out.
Spurs earned just a second win at Stamford Bridge in the past 37 years, with a 2-0 triumph at the home of their rivals.
Mike Penders comically punched into his own goal to put Spurs ahead in the second half.
But there was nothing fortunate about Tel's fine solo effort to make sure of the win and make it back-to-back Premier League wins for Spurs.
Tel has been a hugely frustrating figure for Tottenham, but showed what he can be capable of against the Blues.
And Tottenham expert John Wenham has told the 21-year-old what he needs to do to nail down the left-wing spot for his own after finding himself on the fringes of the squad.
Mathys Tel told what he can do to make starting spot his own
Spurs underwent a huge recruitment drive during the summer transfer window.
That included bringing in the likes of Savio, Mykhailo Mudryk, and Omar Marmoush to improve Roberto De Zerbi's attacking options.
But the left-wing spot has never really had a regular occupant since Son Heung-min departed for LAFC in August 2025.
Wenham thinks Tel can really enhance his own claims to nail it down as his own if he could back-up his goal against Chelsea with a couple more against Crystal Palace this weekend.
Speaking exclusively to Tottenham News, Wenham said: "He came in and what a performance, he was so good on the left-wing.
"I've told you time and time again, that position is up for grabs, since Son left, there hasn't been anybody who has taken up the challenge.
"Imagine, if Tel got a few goals on Saturday against Palace, it would be his.
"Despite the fact that club have signed Omar Marmoush, and so many other attacking signings, the position would be his if he could get a couple of goals in that game, hopefully he does."
Troy Deeney wowed by 'unbelievable' Mathys Tel after what he saw in Tottenham win vs Chelsea Gary Neville U-turned on Mathys Tel live on air
There was quite a comical moment involving Gary Neville live on Sky Sports' coverage of the clash between Chelsea and Tottenham.
Tel had found himself in plenty of promising positions, but had not really been able to deliver the final product.
Indeed, Neville had been criticising Tel for exactly that shortly before his magnificent run and low drive to double Tottenam's lead.
That led Neville to say live on air: "Oh, he's done it. I take everything back!"
The challenge for Tel now is obvious, though, he has to back up what he did against the Blues, and that starts with this weekend's clash versus Palace.
