Manchester United midfielder Shinji Kagawa is 'not satisfied' with the way things have gone since his summer transfer to Old Trafford from German champions Borussia Dortmund.

Kagawa completed his transfer to Manchester United in June of last year after helping Dortmund to the German double, but has scored just twice for the Red Devils during his time in with the club.

The 23-year-old Japan international has, however, struggled with injury since his arrival at Manchester United, and returned to action earlier this month after ten weeks on the sidelines with a knee problem.

Kagawa, though, says it is not just injury that has left him feeling frustrated with his Manchester United career so far, but admits that his performances for the Premier League leaders have not been up to scratch.

"I'm really feeling that I need to perform better," Kagawa said, as reported by

"I'm not satisfied with what I have done here at all. It's a big and really famous club in the world and I need to overcome lots of pressures and be mentally stronger.

"Unfortunately I got injured, but I have to be better and grow as a player a person, in terms of contributing to team's wins and succeeding here."

Manchester United, meanwhile, have confirmed that a fee has been agreed with Crystal Palace for the signing of England international Wilfried Zaha.

The 20-year-old will undergo a medical on Friday, but will not complete his transfer to Manchester United until July, and will instead stay at Selhurst Park to help Crystal Palace's promotion push.
