Barcelona manager Hansi Flick has admitted that Frenkie de Jong is still some way off his best form after returning from a long spell out with an ankle injury.
De Jong has now made nine appearances this season for Barca but still looks a long way short of his best at present.
Flick said after the win over Brest in the Champions League that the club are working hard to try and get the best out of De Jong.
“De Jong is working very hard to get back to his best level.
