Bayern Munich midfielder Hamit Altintop has risked the wrath of boss Luis Van Gaal by venting his anger at being frozen out at the Allianz Arena.
The Turkey international joined the club on a Bosman free transfer in 2007 from Schalke but has struggled to break into the side under Van Gaal's guidance this term.
The 26-year-old has not featured in Bayern's last five games and has gone public with his frustration at not being given the chance to prove his worth.
He told Bild: "I have to reveal I have not shown what I am capable of. I know I am able to do a lot more than what I have shown, this is a fact.
"I have not featured for five matches in a row, this was a really tough decision I feel."
Altintop revealed that he respects Van Gaal's decision-making despite disagreeing with him and has vowed to up his game in training to win the Dutchman over.
"I have a lot of respect for the decisions of the manager, there is no doubt about it, but this particular decision frustrates me," he added.
"I know I am good enough to take part regularly and I need to be in the first team, although I am starting to up my training standard to prove this."
Meanwhile, Bayern midfielder Franck Ribery's move from Galatasaray to Marseille in 2005 is the latest transfer to be investigated for alleged irregularities.
It has been revealed that police have searched the headquarters of Ribery's former club Marseille and seized documents relating to his transfer there from the Turkish outfit.
French police said that accounting and administrative papers were taken as investigators try to determine the movement of funds between the clubs.
Galatasaray originally accused Ribery of breaking his contract when he left for his homeland four years ago but the case has resurfaced after the Frenchman's former agent, Bruno Heiderschied, filed a complaint over alleged corruption surrounding the move.
