It may be purely coincidence that they are preparing to play in a famous fishing town this weekend.

But Carlisle United's preparations to land three points at Grimsby on Saturday have still seen boss Chris Beech trawl through his coaching repertoire for some unusual techniques.

Players this morning crouched on the pitch like "crabs" and took part in an unorthodox small-sided game.

Afterwards, they were asked to lie on their fronts with arms on their backs and wriggle like "salmon", using their heads and feet to manoeuvre the ball along the ground.

Take a look at the club's videos below - we promise there's nothing fishy about them.
