MOTHERWELL last night mocked Manchester United's Alexis Sanchez signing video with a spoof version of their own.

The Scottish Premiership club announced the permanent signing of Blackpool defender Peter Hartley with a Twitter video that poked fun at the one produced by the English giants.

United's film saw new signing Sanchez play the club anthem on the piano before walking into a dressing room to put on his new shirt and step out onto the Old Trafford turf.

In Motherwell's version, Hartley is seen playing a miniature piano badly, pulling on his new jersey with 'Pete' on the back and finally smashing the instrument on the ground.

The video has already had almost two million plays on Twitter since being published on Tuesday evening and earned a response from the official Man United page - a GIF of Sanchez winking.
