Everton manager Sam Allardyce is optimistic club-record signing Gylfi Sigurdsson will be back before the end of the season.
The club suggested in a statement on Wednesday the Iceland midfielder's knee injury would sideline him for six to eight weeks.
"Someone gave out the wrong statement. It can be less than that. Whoever gave that statement out is going to get a b********g today - so well done," said the Toffees boss.
"You cannot predict a length of injury in its entirety because you have people who heal quicker. Obviously Gylfi's recovery time could be shorter than we might expect.
