Arsène Wenger is confident that Ju Young Park will step up to the mark when the time comes in January.

With both Marouane Chamakh and Gervinho set to depart for the Africa Cup of Nations next month, Wenger will be relying on Park to provide competition for Robin van Persie.

Wenger believes the moment will soon arrive when he has to call upon the South Korea captain.

“The adaptation period for him is over now so he has to come in and show he has the quality to play for us,” said the manager.

“I believe he has [the quality]. We also have Arshavin and Oxlade-Chamberlain, who is now ready to play.

“We lose Chamakh and Gervinho for January - two strikers. Maybe Chamakh has not played too many games, but he is still a security that we have. So Park has to step up.

"The problem we have first of all is that we have a big squad. To add players to our big squad, we will have to see how we can balance our books as well.”
