Frank Lampard hopes that Donny van de Beek was only suffering from cramp when he was substituted in the second half of Everton's 1-0 defeat to Man City on Saturday.
The Blues were beaten at Goodison Park thanks to Phil Foden's strike in the second half, despite being controversially denied a penalty after Rodri looked to have handled the ball inside the penalty area.
The hosts lined up with three central midfielders as Van de Beek was joined by Allan and Abdoulaye Doucoure in the centre of the pitch.
