Ronald Koeman was left with plenty of questions after Everton's slump continued with a 3-2 defeat at Watford. And the Toffees boss admits he may have to wait until the January transfer window before he can find the answers.
Everton led through Romelu Lukaku's early strike but were then blown away by Stefano Okaka's first goals for Watford, either side of Sebastian Prodl's header.
Lukaku pulled one back with five minutes remaining but Koeman's side could not find an equaliser and have now won just one of their last 11 matches in all competitions.
"It's strange, and sometimes difficult to understand what happens,'' said the Dutchman.
