Eliaquim Mangala to Manchester City
Manchester City already have a fantastic spine, with Joe Hart, Vincent Kompany, Yaya Toure and Sergio Aguero providing quality throughout.
They also have other options available through the middle with David Silva and up-front with Alvaro Negredo and Edin Dzeko. But that's not the case at the heart of defence alongside Kompany.
Manuel Pellegrini is clearly not a fan of Joleon Lescott, who is now out of contract, whilst Matija Nastasic remains relatively in-experienced at the top level. That leaves a gap which Eliaquim Mangala could fill.
At just 23, the centre back also has plenty of years ahead of him, and has also represented France at international level ahead of the World Cup.
