Robin van Persie: Reason behind striker's decision to leave Manchester United revealed

Robin van Persie was humiliated by manager Louis van Gaal, which forced the striker to leave Manchester United, according to the Mirror.

The player has one year left on his contract at Old Trafford and was linked with a move to Turkish club Fenerbahce. His agent Kees Vos earlier confirmed the Dutchman will report for pre-season training and rubbished speculations.

On his return from a summer break, Van Gaal did not include the former Arsenal captain in the full-training session and made him train alone at Carrington on 7 July. This forced the striker to change his decision and leave his current employers.

Fenerbahce signed winger Nani from United and they were waiting to land the Dutch international. He was keen to continue at United, but the former Barcelona manager's decision to allow him to train alone made Van Persie feel "humiliated".

He informed his agent to accept the Turkish club's lucrative offer of £240,000-a-week ($372,216) after he felt Van Gaal betrayed him. Van Persie is in Istanbul to complete his move to Fenerbahce and the Mirror reports his transfer will see United bag a fee around £4.7m.

Last summer, the striker and the manager were an integral part of the Netherlands squad in the 2014 Fifa World Cup, where they finished third in the tournament. The 31-year-old was backed to flourish under the guidance of his compatriot, who replaced David Moyes.

Van Persie failed to impress as poor form, coupled with injuries saw him struggle in the 2014/15 season. He has expressed his desire to play regular football in the upcoming campaign as he has set his sights on playing for his national side in next year's European championship.

The Super Lig club's chairman Aziz Yildirim has already revealed Van Persie's move to Fenerbahce is a done deal.

"We worked very hard, until midnight. We received five faxes, sent six faxes and finally it was finished. The van Persie transfer is done and one more star has joined the Fenerbahce constellation," Yildirim said, as quoted by the Independent.
