Manchester United midfielder Bastian Schweinsteiger was forced to train apart from the rest of the squad amid speculation that he will leave the club this summer.
The 31-year-old has reportedly been deemed surplus to requirements by new boss Jose Mourinho as United close in on the world-record signing of Paul Pogba from Juventus.
The World Cup winner's future was further cast into question when he trained on his own while the full United squad trained together for the first time on Thursday.
Schweinsteiger only joined United last summer, but he made just 13 Premier League starts for the club, while injury limited him to appearing in only seven of their final 34 games of the season.
Adnan Januzaj was another notable first-team player to be absent from the training session, with Mourinho understood to want to ship out as many as nine players this summer.
United, who begin their season away to Bournemouth, have brought in Eric Bailly, Zlatan Ibrahimovic and Henrikh Mkhitaryan so far this summer.
