Shinji Kagawa will not be leaving Manchester United this summer after Atletico Madrid enquired into his availability, the playmaker's agent has insisted.

The 24-year-old has been relentlessly linked with a move away from Old Trafford after struggling to impose himself on United's first team plans consistently last season, with his former club Borussia Dortmund open to the player returning to the Westfalenstadion.

Reports on Thursday morning suggested that Atletico were hoping to take the Japan international to the Vicente Calderon on a season-long loan, but his agent has insisted he will remain at Old Trafford.

"Shinji will currently not be leaving Manchester United, he wants to fight for his place," Kagawa's agent Thomas Kroth told ESPN.

"Because of the Confederations Cup, he did not have a full pre-season and therefore still has a training deficit. That's why he, until now, has won hardly any playing time.

"Atletico made an enquiry, although this was never an issue for Shinji."

Kagawa endured a mix first campaign during his first season in English football. A knee injury that saw him side lined for four months saw his season peppered with inconsistency as he drifted in and out of Sir Alex Ferguson's first team plans. But the Japanese star provided glimpses of his undoubted talent, chiefly in his hat trick performance against Norwich City in March.

Despite his determination to prove his worth in Manchester, his former employers Dortmund remain keen to resign the playmaker should the opportunity ever presents itself.

Dortmund boss Jurgen Klopp fuelled such speculation by criticising United's perceived penchant for playing Kagawa on the left wing, with the player admitting that he would one day like to return to the Bundesliga outfit.

However United boss David Moyes has made his position on Kagawa's future clear.

"It was his first season in the Premier League last year," the United boss said last month.

"He's a young player so we hope his development continues. I look forward to working with him and hopefully he has a really good season coming up."
