Chelsea boss Jose Mourinho explains the rules of the transfer window to Everton (Video)

A little tension has developed between Chelsea and Everton during this transfer window, with Roberto Martinez appartently irked by Chelsea’s pursuit of his defender John Stones.

Chelsea have made two bids for Stones but have been rebuffed on both occasions, and it’s believed that Manchester United are now ready to swoop in with a bid of their own.

Aware that Everton haven’t been impressed with Chelsea’s advances, Mourinho cheekily took the time to explain the rules of the transfer window to Martinez and co, reminding them that during the window, any club can make a bid for any player.
