The England midfielder was lucky to escape red last night.
The midfielder has already cemented his place in the Tottenham first-team and is also hoping to be in England's starting XI for Euro 2016.
One aspect of his game is starting to worry some experts however. Alli has an aggressive streak. On the one hand it is good but he does sometimes take it too far. He kicked out at Fiorentina defender Nenad Tomovic last night in the Europa League and perhaps should have been sent off.
Speaking to Sky Sports News today (19/02/2016) former Scotland and Aston Villa manager Alex McLeish has had his say on the matter - describing what he would do to sort out this aspect of Alli's game:
"I think it is about managing him. He is a young guy and he needs to learn that if the coach loses resources in a game and one of the players gets sent off then it costs the team.
"It's all about the team and not the individual. He (Mauricio Pochettino) has to hammer it home to Dele Alli that he can't be seen to be doing things like that.
"It's a man-management situation. You don't have to be hard on the player, you' don't have to be rough with him the way you speak to him. You can give him the correct words.
"If we lose a game (because you get sent off) everyone will point at you and to the fact you did something stupid."
The midfielder's 'streak' as it is beginning to be known should not be taken away from him. That little bit of nastiness is what sometimes separates the good from the excellent in professional football.
However, as McLeish points out, it will eventually see him sent off and potentially cost Spurs or England a game in the future.
