Several of Alexis Sanchez's Chile teammates have reportedly remarked on the Manchester United attacker's 'strange' behaviour while on international duty.
Sanchez's future at Old Trafford has been the subject of much debate in recent days amid reports that he wants to leave the club in January - just a year after joining from Arsenal.
The reports have suggested that Sanchez has struggled to settle into the area and the team and often cuts an isolated figure in training.
La Tercera claims that the 29-year-old has also been acting out of character with Chile, reporting that he sat silently near a training pitch on his own for more than an hour while his teammates played football tennis nearby.
Sanchez has fallen down the pecking order under Jose Mourinho this season, having scored just four goals in 29 games since joining the club in January of this year.
Chile's all-time record goalscorer is understood to want to join Paris Saint-Germain, but the Ligue 1 giants have reportedly decided to focus on other targets when the transfer window reopens.
