"And then before you know it he's hit the ground running and he's now not only a key part of Dortmund's team but from England's point of view, come March it wouldn't surprise me to see him starting out here at Wembley".
"We knew very well that he was capable to do what he is doing now with game time", said Pochettino.
"One goal and an assist!" We need to feel proud about the performance, so happy but at the same time, calm, because there is still a lot of work to do. It was a fantastic game, a massive effort. "My players are heroes", he added.
"3-0 is a very good result but it is only the first leg". Of course 3-0 is a very good result but when you have in front a team like Dortmund you always need to respect them.
Playing some pretty extravagant football at times, Mauricio Pochettino's side were no match for the tempo which Dortmund set and were playing catch-up for nearly the entire first period.
Youngster Kyle Walker-Peters is one option that could slot in at left-back, while senior versatile defender Jan Vertonghen would be the other and perhaps the safer bet. Maybe today everyone will say it was a fantastic decision.
"The first half was very hard". We didn't feel what we planned to play.
"We were a little bit lucky because when Son scored it was a massive boost to our confidence".
Spurs broke the deadlock two minutes into the second half through Son Heung-Min, who sent a fine volley past Roman Burki from close range. We should get the ball forward rather than try and play. That was a gift.
The Daily Express framed Pulisic and his "underwhelming performance against Tottenham" in the context of replacing star Eden Hazard (who is expected to join Real Madrid this summer) and noted that "fans on Twitter were not impressed at all by his performance at Wembley on Wednesday night".
Dortmund were without the services of talisman Marco Reus as Chelsea-bound Christian Pulisic was drafted into the attack.
But Lloris spared Foyth's blushes as he blocked Pulisic's shot at the near post.
Wenger, who long had a reputation as a manager willing to turn to young players, also believes that the amount of money on offer to players like Sancho before they've earned it on the pitch could be hampering their drive to improve.
Sancho has had a stunning first full season in the first team at Borussia Dortmund.
