Arsenal boss Arsene Wenger admits he hasn't been fair with Park Ju young.

Wenger accepts the 26-year-old has to go through a period of acclimatisation following an August transfer deadline move from Monaco.

"It has been difficult because I have not given him the chance to play and the intensity of the challenges - some players take short, others take long. But it takes you time," said the Arsenal boss ahead of the meeting with Wolves.

"You see a player like (Laurent) Koscielny last year, he was still sometimes surprised by the physical demands of the game. This year, he is dominating the physical challenge, that shows it takes time."
