Mikel Arteta played down the big picture of this result - namely, that it makes them the favourites to win the Champions League - but he was happy with what he saw, particularly given he had to rotate some fringe players in.
'The overall performance thd the way we dominated the game [pleased me],' he said.
'We knew this game was going to require a different dimension, and individually we were exceptional.
'It will bring more confidence and trust to the players [seeing rotation players performing].
'We had an issue with Leo [Trossard] so we had to take him off.
'We're still so far [from winning the CL]. We have a really good record so far but tomorrow we prepare to go to Stamford Bridge.'
Thomas Frank was disappointed at the two goals Tottenham gifted to PSG, but generally happy with their performance in a 5-3 defeat using an altered 4-4-2 formation.
'I'm very pleased with the performance. Today was much more the identity of the team - the aggressivity, the bravery, running at them,' he told TNT Sports.
'The two strikers scoring three goals between them. The whole team. Archie Gray and Lucas Bergvall looked really good.
'The two goals, three and four, you can't concede them here. [But] Vitinha will be the next Ballon d'Or winner for me.
'The two goals give [Kolo Muani] confidence to go forward. He had a dead leg, broken jaw, came to us not fit. He saw the better of him today.
'Conceding four then five will always be concerning but they are two completely different games and I take the positives. Today I saw a team with soul and character and you need that.'
A huge statement from Declan Rice: Arsenal's mentality is better than it has ever been before, he says.
'I think so [the mentality has changed]. There are a lot more leaders in the team now. There are players who have been at the club for a while now. It hurts not getting over the line. The mentality has been different this year. There's a hunger and a desire to win every game and we can do that at our best.
'There's a long way to go.'
Some interesting points from Rice on TNT Sports. Apparently, not much practice goes into those venemous set-pieces...
'We knew tonight what we were in for: probably the toughest game tactically. They've been the best team in Europe.
'Second half we did much better, got our references right, went man to man.
'It's been so easy to play with him [Zubimendi]. From the first moment e had with each other in pre-season, I could tell we were going to play some good football. I really liked him as a person and a player. He's Spain's number six and you know what Spanish number sixes are like! He's an unbelievable player.
'The players all believe in him [Arteta] and what he does. Chelsea will be a different game tactically but every player knows their role.
'Delivery is a big part of it [my set-pieces]. We don't actually get to work on it a lot because of the game schedule nad how much you have to work on the opposition. But it's something we've built in for a while now.'
Is it too early to start talking about a quadruple challenge?
Previous seasons have taught us that things can unravel quickly. Hey, Liverpool are a case in point right now.
But Arsenal are so clinical, so impregnable. Their depth is actually quite scary, particularly at full-back and in the attacking areas. They've had injury blows this season but marched on unflinching.
They proved last season that they could beat Real Madrid. This season they've scalped Bayern, battered Atletico Madrid, demolished Tottenham.
Who can stop them?
'Two years ago they couldn't have won this game. That second half, I thought they dominated,' said Owen Hargreaves on TNT Sports.
'It's the same performance but different players. It's a mentality thing,' says Martin Keown.
Noni Madueke has been speaking to TNT Sports...
'First of all I just want to thank my Lord and saviour Jesus Christ.
'Couldn't have picked a better game for my first goal. I'm so happy that the team got the win as well.
'It's an incredible statement but we know the work that we put in every single day. We go into these types of games with the confidence that we can get the job done.
'I'm a confident player so I don't like anyone telling me I can't do something [responding to summer criticism]. But the belief the players and staff have in me is the reason I want to [do well here].'
