Arsenal new boy Park Chu-young has scored an international hat-trick to celebrate his move from French club AS Monaco.

The 26-year old fired home a treble for South Korea as they hammered Lebanon 6-0 in their opening 2014 World Cup qualifier in Goyang.

Park, who signed with Arsenal earlier this week, grabbed his first-ever hat-trick for the Taeguk Warriors with two goals in the first half followed by a fine finish with just over 20 minutes left.

Sunderland striker Ji Dong-won scored twice in the rout with Kim Jung-woo also chiming in as Cho Kwang-rae's men kicked off their Asian qualifying campaign in fine style.
