£30m Rio will blossom into world's best, says Ferguson

ALEX FERGUSON claims Rio Ferdinand will blossom into the best centre-half in the world now that he has finally become a Manchester United player.

Ferdinand signed a five-year contract with United after completing his British record £30million transfer from Leeds and Ferguson has no doubts he has bought a real talent.

Ferdinand is already regarded as one of the finest defenders in the Premiership following his star performances for England at the World Cup and Ferguson says he can only get better.
