Man United Transfers: 4 Replacements For Rio Ferdinand

4. Raphael Varane

To kick of this list, we have the young French centre back Raphael Varane. Signed from Lille in 2011, he has certainly flourished in Madrid in the two years since.

In terms of the first criterion Moyes wants for a central defender, he is not experienced in the sense of his age (he's only 20), yet he is experienced in terms of being entrusted with first team football at the Bernabeú (25 appearances last season) and playing against the best that European football has to offer and arguably performing admirably against them. Two appearances for his national team as well signifies his worth to all parties. His assured nature he presents on the pitch exudes confidence throughout the Madrid team and that quality is much admired in a United squad and the best part is he has many successful years ahead of him where he can only improve and become one of the best centre backs of his generation under the tutelage of experienced United contemporaries such as Nemanja Vidic and the vastly improving Jonny Evans, who looks likely to become his long term partner if Varane lands at Old Trafford.
