Wenger backs Park for success

However, the under-fire manager believes the player's ability to cover a wide range of positions will come in handy in the long season ahead.Park is expected to make his debut against Shrewsbury in Tuesday's Carling Cup third round tie along with Japanese teenager Ryo Miyaichi.Arsenal boss Arsene Wenger is confident Park Chu-young will become a key player for the club.Wenger signed the South Korea international from Monaco just before the transfer deadline but the 26 year-old has yet to feature for the Gunners."Park is good in every area. He is good in the air, good technically, he is mobile and that's why he is an adaptable striker who can play up front behind the striker," Wenger told the club's official website."That's why we went for him. What I like with him is that he is very mobile and that's the basis of our game."
