British heavyweight boxer, Tony Bellew, believes Manchester United boss Jose Mourinho's recent complaints is a sign that his days may be numbered at the club.
Mourinho bemoaned Manchester United's lack of signings following their 4-1 loss to Liverpool at the International Champions Cup.
United have been linked with a host of stars but so far only Fred, Diogo Dalot and Lee Grant have arrived, with Mourinho making no secret of his desire for the club's hierarchy – led by Ed Woodward – to deliver reinforcements in his quest to catch reigning champions Manchester City this season.
But Bellew, a self-confessed Mourinho fan, stated he feels the Portuguese coach may be seeking fresh challenges elsewhere.
"I don't think he's got anyone to blame but himself. He is the man in control at Manchester United, he determines who comes in and who goes out," Bellew said as a guest in Alan Brazil Sports Breakfast Show.
"I don't quite get what the moaning is about, "I haven't got the players I want, this is not my squad"," the former WBC cruiserweight and ABA heavyweight champion said.
"Let's be honest he's been there for two years and if it's not his squad whose squad is it? He's had four transfer windows to make it his squad and do whatever he wanted to do. He spent a lot of money and bought in the likes of Paul Pogba, Romelu Lukaku in record-breaking transfer fees.
"Believe it or not I'm a huge fan of Jose Mourinho, I think he's a fantastic manager. It's truly amazing what he has done but is he playing gamesor down playing his season ahead because to be honest it's just looking like typical Mourinho syndrome where he's had the two seasons at the club and has it now got to the time he's had enough? had a couple of arguements with senior players and they will turn on him.
"I don't just know what it is about him. Does he want a new challenge? does he want his money and get out? I just don't know. I'm a huge Mourinho fan. I want him in English football, it's for our benefit. Which manager is outspoken as Mourinho because the managers these days are so in peace.
"It's just interesting how Manchester United starts, whether they will hit the ground running but one thing is for sure, teams like Manchester United has to be in the Champions League, one of the biggest clubs in the world if not the biggest club, and they have to be there otherwise he's regarded as a failure and he will be out the door before you know it."
