Manchester United released pictures showing Bastian Schweinsteiger and Henrikh Mkhitaryan in first-team training on Monday.
Schweinsteiger, signed by Louis van Gaal in 2015, had not been training with the first team following Jose Mourinho’s arrival in the summer.
However, United published a picture on Monday showing the pair in training alongside midfielder Marouane Fellaini and assistant manager Rui Faria.
Schweinsteiger said in August that he “will be ready if the team needs me” but United subsequently wrote the former Germany international off as an asset in the club’s accounts.
