Dele Alli is a doubt for Tottenham's Premier League match with Everton on Monday 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 about a press conference 48 hours before the game is there's still a session tomorrow so you will not know what I know, if he is available or not.
