The Chilean has reportedly been showing his frustrations with his club career while on international duty this week
Alexis Sanchez is said to be at his lowest ebb since joining Manchester United.
According to an exclusive report in The Sun, the Chile striker has been “acting weird” on international duty this week.
It comes after Sanchez was left out of the starting XI for United’s derby clash with Premier League leaders Manchester City on Sunday.
The 29-year-old appeared off the bench for only the final 17 minutes in his side’s 3-1 defeat the Etihad.
Sanchez was reportedly furious at his omission and “slammed his boots down” in the dressing room after the match.
His frustrations are claimed to have been apparent this week, with Sanchez cutting “an isolated figure” in training with Chile.
According to Chilean publication La Trecara, Sanchez sat on one of the training pitches on his own for more than half an hour after a session, while his team-mates were nearby playing football tennis.
He was persuaded to join in with the other players, but his behaviour was described as “strange” by some of his fellow Chile stars.
Sanchez was a high-profile signing for United from Arsenal in January but has yet to show anywhere near his best form under Jose Mourinho at Old Trafford.
He has scored just three goals in 21 Premier League games for United and has so far started only five league games this season.
A source told The Sun: “He is totally fed up and at the end of his tether with Mourinho. He knows he can’t leave right now but is in talks with his agent about what they can do to try and sort the situation out.”
