Tottenham manager Mauricio Pochettino criticised Dele Alli for a diving incident which he said was unhelpful to the team, in a 4-0 win which revealed the best and worst of him.
Alli was clearly guilty of simulation in the game's closing stages, as he attempted to round Huddersfield Town goalkeeper Jonas Lossl.
'I didn't see,' Pochettino said. 'It's so difficult for me from my position. But if it was like this he needs to learn. He must learn. This type of action doesn't help him, doesn't help the team and doesn't help the football.
He added: We are talking in the last few years about fair play, about being honest.
