Having coming under fire for high ticket prices in north London, Arsenal owner Stan Kroenke is now being attacked on the other side of the Atlantic for his ownership methods.

The Gunners owner has been the target of protests following his club's decision to charge season-ticket holders an extra fee for cup games this season, despite Arsenal's price freeze. The move has since been overturned following outrage from fans.

And now he is the subject of another high-profile outcry, this time in America, where his NFL franchise have come in for criticism.

Kroenke, as owner of the St Louis Rams, made the controversial decision to move the franchise to Los Angeles, where they played until 1995, for the next NFL season.

And now one local lawyer has taken out an advert in the Super Bowl to complain about the move, as well as starting the hashtag #SlamStan.

Terry Crouppen accuses Kroenke of 'trashing' St Louis before leaving, and tells him 'Just because it's legal and you're rich enough to do it - that doesn't make it right'.

The advert will be shown in full at half time in the Super Bowl on Sunday, for which a 30-second spot can cost as much as $5m (£3.45m).

The hashtag has taken off since he released the advert, with Arsenal supporters joining American sports fans to show their displeasure.
