Spanish television show El Chiringuito de Jugones discussed the relationship between the two, and claimed that the two have clashed in recent weeks, leading to a "complete breakdown" in the relationship.
It was a near faultless performance from the Argentine but Pochettino was happy with how Spurs dealt with him in the first half although conceded he was hard to stop as the game developed.

The five-time world player of the year could even afford to hit the post twice before scoring in the second half as the five-time European champions made it two wins out of two in Group B.

Everybody who will play the game in the future will also be struggling to match him.
"I think our players were heroes because to chase the game, playing against Messi, Suarez, Coutinho and company, and be competitive in the second half".

Lucas Moura then forced Ter Stegen into a save from 19 yards out after picking up the ball in midfield and running at the defence on 81 minutes, and the Brazilian saw his goalbound strike from 10 yards out deflected wide of the left post by Lenglet three minutes later.
Thirty-two seconds after the second of those let-offs for Spurs, Kane dragged them right back into the match with his curled finish past Ter Stegen after working the ball onto his right foot.
But the damage was done due to defensive errors from Lloris and Sanchez as they badly missed Vertonghen's calming influence and Dembele's presence in front of the back four.
