Tottenham Hotspur boss Mauricio Pochettino revealed that he has warned Dele Alli over his discipline after causing a stir in last week's 1-1 Europa League draw away to Fiorentina.
The 19-year-old midfielder was deemed fortunate to stay on the field in Florence after appearing to lightly kick Nenad Tomovic in the stomach, for which he received a yellow card.
Alli insisted that he apologised to Tomovic on the night, but the talented Lilywhites youngster was unapologetic for possessing an aggressive streak in his game.
There have been suggestions that the Viola could exploit his tempestuous nature when both sides conclude their last-32 tie at White Hart Lane on Thursday, but Pochettino is confident that he will handle his emotions better this time around.
“We had a very good chat, and I think it was important," the Argentine is quoted as saying by reporters, via the Evening Standard.
"He is very young and needs to learn, but he is a very nice guy. He is very competitive on the pitch and has shown he is one of the best players in England. It was a normal chat and it showed for the future that he has learned a lot.”
Alli's discipline has been a rare negative in an otherwise hugely positive breakthrough season, which includes seven goals from 20 Premier League appearances.
He joined from MK Dons last February, before being loaned back immediately for the rest of the 2014-15 season.
