Shinji Kagawa has admitted that he feels irritated that he did not score in the first-half of this Premier league season, and is struggling to find his place at Manchester United.
"I still haven't scored any goals this season so I've felt very irritated," the Japanese star told Sky Sports.
Kagawa, 24, has played nine Premier league games for United this season, but only completed 90 minutes twice and has not yet managed to put the ball in the net.
He added: "This is the first time in my career that I haven't been able to produce so it's disappointing."
However, with the arrival of Juan Mata at Old Trafford, the ex-Dortmund man has a world-class rival to beat to be considered as a first-team regular, which may awaken a sense of competition that could prove to be beneficial in the long run.
The Japan international arrived at Manchester United in the 2012 summer transfer window, where he already faced some difficulties by scoring just six goals in 20 appearances in the 2012-2013 season.
At Dortmund, the 24-years-old scored 10 goals in 24 appearances in all competitions when he joined 2010-2011 from Cerezo Osaka, and improved his scoring record by four in the following season which took him to 14 goals in 37 appearances.
Although Kagawa had his moments last season, especially with a hat-trick against Norwich, it is clear that he has not yet improved as a footballer during his time at United.
The ex-Dortmund playmaker still has time to get better this season and convince David Moyes that he is worthy of the red shirt he wears, but he is going to have to work extremely hard to put himself ahead of Mata in the pecking order.
