Watch Theo Walcott pretend to fall down the stairs in behind-the-scenes video at Everton medical

Theo Walcott completed his £20million move from Arsenal to Everton on Wednesday and fans were treated to a behind-the-scenes access to the day. 

The winger posted a series of videos on his Instagram story showing him on his way to his Everton medical and posing with his new shirt. 

At one point, Walcott even pretended to fall down the stairs at the Toffees' training ground Finch Farm! 

This was Everton's second major signing of this transfer window with Turkish forward Cenk Tosun arriving from Beskitas last week.
