#2 Kourt Zouma (On loan at Everton)

Kurt Zouma can be a long-term solution to Chelsea defensive problems. The Blues have not been able to replace John Terry since the veteran defender left the club in 2017. Chelsea have conceded 39 goals in the Premier League this season while Zouma has been impressive at the heart of the defence for Everton.
Zouma's impressive performances for the Toffees earned him his first appearance for France in over three years. At only 24 years old, the French defender has his best years ahead of him and could form part of Chelsea defensive line for a decade.
Gary Cahill is likely to leave the Blues in the summer while David Luiz is also aging, therefore this is the perfect opportunity for Zouma to step up and nail down a starting berth as he will inject more pace and solidify Chelsea's porous defence.
