Manchester United’s title glory is bittersweet for Shinji Kagawa.
The Japanese international arrived at Old Trafford from Borussia Dortmund amid much fanfare at the beginning of the season.
He was meant to be the Red Devils’ new go-to guy in central midfield, but took his time adapting to the pace of the Premier League.
Michael Carrick, Tom Cleverley, Paul Scholes and Wayne Rooney have all played in the playmaker's position United had hoped Kagawa would make his own.
And the 24-year-old Samurai Blue star cannot help but feel that in part due to injury, and in part due to his form, he did not contribute as much to United’s success as he had hoped to.
He scored five goals, including a hat-trick, in 18 Premier League outings, and if anything, Kagawa’s appetite for success at Old Trafford has only been whetted, not satisfied by United's 20th top-flight title.
"I was looking to produce even more results. I was injured and I felt things didn't go well easily,” Kagawa said, according to Sky Sports.
"I had a lot of conflict, frustration and worries. In that sense, I think it has been a profound year.
"Honestly, I haven't contributed as much as I did at Dortmund.
"I was even injured. I still don't quite have that feeling of accomplishment."
However, Kagawa is confident that his United career is on the up. After all, he has just won his third league title in as many years, having won two in a row in Germany before he made his career-defining move to England.
"I've managed to win three in a row,” Kagawa said. “I think my career is bound to get better and better."
