Everton submitted a deal sheet to the Football Association in order to secure extra time to finalise all the details of the move, and Zouma will now be preparing himself to join up with his new teammates.
The Toffees made a late move for the 23-year-old on deadline day but had to wait until Friday to learn if their bid had been successful.
The French global spent last season out on loan at Stoke City but couldn't prevent them from being relegated from the Premier League and he's now facing an uncertain future back at Chelsea under Maurizio Sarri.

Chelsea's stance over the interest from Manchester United gives Everton a major boost to land him on a loan deal, with the Toffees going into overdrive on deadline day.
Manchester United's search for a defender this summer was so embarrassing that it could even be described as farcical, however, it has been revealed that they actually turned down to the chance to sign Yerry Mina.
