Alexis Sanchez is set to leave Arsenal for Manchester United on bad terms with Laurent Koscielny.

Goal says the Chile international's poor body language has not sat well with some of his Arsenal team-mates.

Koscielny supposedly called Sanchez out after games against Burnley and Southampton this season, criticising him for what he perceived to be a lack of effort.

It is said the Frenchman has regularly been clashing with the United target throughout the season with the Burnley and Southampton incidents far from isolated.

It's also claimed Arsenal have covered up some of Sanchez's misdemeanours.
