Former Manchester United defender Rio Ferdinand rates English players as over-valued.

Ferdinand, who's move from Leeds United to Old Trafford was a world record for a defender at the time, took to twitter:

English players are soooo overpriced right now it's a joke! Kane & sterling have huge potential but 40m & 50m...aguero 38m & sanchez 32m!!! — Rio Ferdinand (@rioferdy5) June 20, 2015
