Arsenal boss Arsene Wenger says Gervinho's impact has been affected by his African Nations Cup commitments.

Wenger is confident Gervinho will prove his quality in the remaining weeks of the season.

"For me the big problem in the last two years has been the Africa Cup of Nations. Every time he came back it took him a while to recover.

"But I thought when he came on at Swansea last week he was lively. At Bayern he was lively and he scored the goal on Saturday which gave him confidence again."
