Manchester City star Ilkay Gundogan has branded Jose Mourinho "disrespectful" for his treatment of Bastian Schweinsteiger and believes Manchester United could "100 percent benefit" by playing him.
Schweinsteiger was lauded by Louis van Gaal after arriving from Bayern Munich last summer but the veteran midfielder failed to make an impact after suffering from fitness issues for much of the campaign.
Instead of nurturing the 32-year-old through the twilight of his career, Mourinho decided to throw him out of the dressing room. He made it clear the German would not be part of his first-team plans and urged him to leave Old Trafford.
Despite several offers, Schweinsteiger decided to remain but Mourinho has stayed true to his promise and refused to name him in any of his matchday squads so far. That is despite the fact that Paul Pogba is in clear need of extra support in the centre of the park.
For Gundogan, who himself arrived in Manchester this summer as part of Pep Guardiola's revolution, Mourinho is making a mistake by continuing to leave Schweinsteiger out.
He told ESPN: "I believe that Manchester United could 100 percent benefit from a fit Bastian Schweinsteiger."
The 25-year-old also believes Schweinsteiger is not deserving of the treatment he has received from Mourinho.
Gundogan added: "If everything you hear and read is true, you can consider it disrespectful. He's not just some player, and also not only 18 or 19."
Although Premier League fans are quickly forgetting that Schweinsteiger ever played in England, he remains a hot topic of conversation in his native Germany, where he is rightly considered a legend after winning 121 caps for the national team.
That is perhaps why Per Mertesacker was also asked for his opinion on the situation in a recent edition of Kicker Magazine. The Arsenal defender is one of a number of Germans to have enjoyed a successful experience in the Premier League and believes Schweinsteiger is simply the victim of bad luck.
"It's bad luck for him that he joined a club that has again changed its manager, and that the new manager does not want him," the Gunners captain told Kicker. "It can happen to you at any time in this business, and it's a bit perverse, but Basti signed a good contract, and he knew where he was going.
"He just had bad luck with the way it worked out. He will draw his conclusions and I wish him all the best."
Schweinsteiger has stayed respectful to Manchester United throughout the ordeal and stated it would be his last club in Europe.
A move to MLS club FC Dallas has been mooted in recent days.
