Tottenham boss Mauricio Pochettino is prepared to help struggling midfielder Dele Alli rediscover his best form.

"His success in two and a half years is massive, a fantastic achievement," said Pochettino.

"It's not that he isn't doing good - the problem is that in the past he was amazing.

"Sometimes to be consistent, a player needs to go down to come back up. The most important thing now is support from the club and the coaching staff, to trust and help him reach the same levels as before."
