Arsenal forward Alexis Sanchez is reportedly unhappy at the club after falling out with several players.
The 25-year-old has made an instant impact in North London since making a £32m move from Barcelona in the summer, but he is said to be disappointed with how things have panned out.
South American publication La Tercera claims that Sanchez felt aggrieved not to have received more support from Mesut Ozil on the field, which led to discontentment among Arsenal's players.
The same report suggests that Sanchez, who has eight goals in 15 appearances for the Gunners this season, has questioned the work ethic of the group, and is particularly displeased with Ozil's contribution.
Arsenal are currently fifth in the Premier League table.
