6) Juan Sebastian Veron – Argentina
Veron has to go down in history as one of the biggest wastes of money ever in the Premier League, with nearly £30m spent on the Argentine in 2001.
He failed to adapt to life in the Premier League however, and lasted just two seasons at Old Trafford.
The midfielder was a key player for his country however, and with 73 caps he was a vital part of Argentina’s success in a number of major tournaments.
