Despite winning against Valencia in the end on Wednesday night, Ji-Sung Park admitted that his performance was under-par and that he is looking for self-improvement to retain his place in the United starting line up...

Javier 'Chicharito' Hernandez was The Red's saviour from the bench, netting in the 85th minute, after coming on just a few moments earlier. Ji-Sung Park was one of many under-preforming United players on Wednesday night, but the South Korean captain was the only one who held up his hands and said he wasn't good enough.

"I am not satisfied with my performances this season. I don't know why my performances have not been good. Maybe I was not ready for the season. But mentally I have been weak and I have to improve. In the first-half last night my performance was bad but at least the second was better."

"It is always difficult to get the balance," said the 29-year-old. "I missed a couple of games and then played again, although since I joined Manchester United it has been like that so I should know how to deal with it." 

Speaking about the absence of talisman Wayne Rooney, Park added: "Throughout Manchester United's history we always come up with answers to problems. Big stars come and go but still the team keep producing the same performances. We just concentrate on that to make sure we show our quality on the pitch..."
