Shinji Kagawa has revealed that former Manchester United manager David Moyes didn't 'count on him' during his time at Old Trafford.
The Japan international returned to Borussia Dortmund in the summer transfer window following two failed years at United.
The midfielder struggled to force his way into the Red Devils first team, and as a result, was sanctioned a move by manager Louis van Gaal.
"Everybody knows that my second year at Manchester United was particularly difficult," Kagawa told reporters. "The manager did not really count on me, and the team was also on a bad run.
"That means I am all the more delighted to be back. My heart had remained at Borussia Dortmund anyway."
Kagawa spent two years at the Bundesliga club prior to moving to United.
