Rating: £16 million
The Nigerian international caused some controversy when he first came to England when Manchester United announced that they had agreed a deal to sign him from Norway, only to see the player announce that he had been coerced into signing a contract with the Champions.
After much toing and froing the three parties agreed that Chelsea would pay United £12m for his registration, as well as £4m to Lyn - the original fee Man Utd had agreed to buy him for.
