Reportedly, Manchester United are desirous to sign him permanently, whereas the Toffees only want a loan deal. Now, it seems they have set their sights on Chelsea outcast Zouma. After two years of gradual progress within the first-team setup at Stamford Bridge, the player saw his development come to a grinding halt when he sustained a major knee injury.
Zouma spent last season on loan with Stoke too but had to deal with relegation at the end of the season.
It might be hard for him to get regular playing time at Chelsea this season, so sending him out on loan makes sense.
But, the Manchester United boss has only been met with disappointment in his bid to sign a centre-back, the latest coming in the form of Diego Godin's reported rejection.
Signed from Burnley last summer, the 25-year-old defender arrived at Goodison Park as a highly-rated player who had pushed his way into the England set-up but he has fallen down the pecking order in Gareth Southgate's squad in the past 12 months.
Zouma was signed by Mourinho in 2014 when he was the manager of the London based outfit.
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.
