This season, Manchester United's performance has been heavily criticized, and the captain Tannhäuser was even in danger of being fired. Looking back on his coaching career at Manchester United from 2016 to 2018, he had expelled an "internal tumor" from the team, and this "tumor" is the English left back Rauki Suhr. Recently, Tannhäuser, in an interview with the British media, spoke frankly about the internal environment of Manchester United, suggesting that the "tumor" of six years ago still exists in the team.
After leaving Manchester United, Tannhäuser has coached Tottenham and Roma and said in an interview with the Daily Telegraph, "Manchester United have several players that I wanted to get rid of five or six years ago. With the size of United, I believe time will tell. I sincerely hope United will be successful."
In Tanhag's final season in charge, United still retained players in their squad including Lauki Suhr, Rashford, Anthony Martial, Luke Shaw, Dalot and Mike Tommie. The British media pointed out that Lauchysaur became the prime target of Tanhag's criticism, which is not unrelated to the conflict between them. Not only did Tanhag openly question their form, he also blamed their attitude to the game.
