Louis van Gaal's decision to criticise the form of Bastian Schweinsteiger came as no surprise to Manchester United fans, who themselves have been underwhelmed with the German's impact thus far.
But it has left Bayern Munich chief executive Karl-Heinz Rummenigge feeling rather disappointed in the Dutchman, who believes Van Gaal has treated Schweinsteiger unfairly.
The 31-year-old made the move to Old Trafford in the summer after 13 years with Bayern Munich's first-team. Although he arrived with a stellar reputation, Schweinsteiger has yet to fully adapt to the rigours of English football.

Following another poor display against West Ham, Van Gaal told German reporters that he is yet to see "the best of Schweinsteiger" and said "he could have played better" in every one of his 23 appearances for his new club.
But Rummenigge believes Van Gaal's criticism is premature, advising the former Bayern Munich manager to leave his new signing alone, and reminding him how badly he wanted to sign him in the summer.
Rummenigge told Bild: "I am a bit disappointed by Louis. He should leave Bastian alone, he absolutely wanted him, Bastian will take a little time. You can't now pass judgement on him."
Bad to worse
While Van Gaal may be wrong to publically air his frustrations with Schweinsteiger, he has every reason to be angry with the World Cup winner. Indeed, he was brought to the club in order to bring experience to the dressing room but acted like a petulant teenager against West Ham United on Saturday.
He appeared to elbow Winston Reid in the face and now faces an FA violent conduct charge. It has recently been announced that he is ready to contest the charge, but if found guilty he will be banned for the next three games.
