The World Cup winner joined Louis van Gaal's United in 2015 from Bayern Munich, where he had previously played under the Dutchman.

However, after struggling in his first season at Old Trafford - making just 18 Premier League appearances - Schweinsteiger has been absent from the first team under new manager Mourinho, instead training on his own.

When United tweeted its latest squad picture on Friday (AEDT), Schweinsteiger was omitted. 

Eagle-eyed supporters also noted the absence of the FA Cup - a trophy won by Van Gaal - from the image, with Mourinho accompanied by under-fire captain Wayne Rooney.

United sits seventh in the table, six points behind leader Manchester City, which it knocked out of the EFL Cup this week.
