The reason Boateng rejected United

Mourinho turned to the World Cup winner in a bid to secure a quality addition to his squad at centre-back, but instead received a call telling him that the former Manchester City man was not interested in the move.

According to 'Sky in Germany', Boateng has set his sights on winning the Champions League once again in his career and feels that United are not likely to challenge for this season's iteration of the competition.

Boateng turns 30 in September and had previously admitted his interest in trying out a new challenge, but after talks with Bayern boss Niko Kovac he now looks set to stay put.

Reported interest from PSG has gone quiet amid their concerns over meeting Financial Fair Play requirements, but the 29-year-old could be tempted by a switch to the French capital should a suitable deal materialise before the deadline.
