Tottenham midfielder Dele Alli has suffered an injury setback.

Alli is a doubt for Tottenham's clash with Everton after picking up a hamstring injury in training.

The England international, who has a history of such problems, picked up the issue on Saturday, but Jose Mourinho does not know if he will be fit.

"Something today in training with Dele Alli," Mourinho said. "I don't think it's big. I don't really know what it is.

"The bad thing of press conference 48 hours before a game is another training session tomorrow.

"Hamstring, which is something he's had problems with in the past, even in this season, and is always something that makes the medical department think about it.

"We all think that it's nothing important. If you ask me in this moment I think he will be available but I don't know."
