Jesse Lingard, Ander Herrera, Ashley Young and Marcus Rojo were all absent from Manchester United training on Monday morning, but Paul Pogba looked in high spirits.
The Reds are preparing for a home clash with Valencia in the Champions League on Tuesday evening after losing to West Ham United at London Stadium on Saturday.
Pogba's rift with Jose Mourinho caught the headlines last week after the Portuguese stripped the midfielder of the vice-captaincy and the pair clashed at United's Carrington training complex.
However, the France international started against West Ham, although he was substituted in the second half after an under-whelming performance, and was photographed smiling while warming up for training on Monday.
