It has been a tough time for Shinji Kagawa since making his move to Manchester United from Borussia Dortmund in the summer of 2012 - costing the Red Devils £17million.
Despite being named in the Bundelisga team of the year, the Japanese midfielder has failed to put a string of games together where fans are left smiling.
The creative no.10 role he enjoys playing is occupied by Wayne Rooney, who after signing a new five-year contract will only worsen his chances of playing in this position. So what can David Moyes do?
Football has moved on from the standard 4-4-2 formation that Moyes has played most of the season and with teams like Chelsea and Manchester City playing three behind the striker, many believe Moyes needs to do the same.
Against West Brom at the weekend, United played some of their best football in the second half to score two goals in a 3-0 win. The first of the two came from Rooney. Having moved into the middle from the right, Mata played a neat one-two with Rooney before Rafael delivered a lovely cross for the striker to nod home.
The second came with some passing football which was started deep in their own half. United managed to defend a cross and from winning possession, Fellaini, Kagawa, Mata and Rooney all combined in a 40-second keep the ball process which was finished off by Danny Welbeck.
It was good to see Moyes finally letting his players enjoy themselves and roam around freely causing problems with movement and triangles.
Ashley Young and Antonio Valencia did not feature and something about the side looked more attacking and potent in front of goal.
Young, who gave the ball away 24 times during the 2-0 defeat away at Olympiacos was dropped and Valencia was not in the squad due to international duty.
Adnan Januzaj started on the left of a three-man attack and looked lively delivering good crosses. Mata on the right mixed up his game cutting in, as well as linking up with Fellaini and Carrick.
Rooney was his usual self, giving 100 percent and trying to ensure United got back to winning ways. In the 15 minutes Kagawa was given, you could see glimpses of what the 24-year-old could produce - given a run in the side.
A front four of Rooney, Januzaj, Mata and Kagawa behind Robin Van Persie is the perfect fit for United moving forward and many wouldn't argue if that was the case next season.
Allow the likes of Valencia and Young to leave and Moyes can start using his world class players to deliver on big match days. Relying on Ferguson's old guard who should be coming to the end of their careers at the club isn't his challenge. The real challenge is getting the best out of his best players and they are this front five.
United take on Liverpool Sunday before testing games against Olympiacos, West Ham and Man City where all four should figure behind Van Persie, who continues to play despite rumours of unhappiness.
