Let's put the fee for Vidal into perspective.........
In 2010-11, Vidal is rated as the 3rd best central midfielder in Bundesliga after Nuri Sahin and some other player. Sahin was also in the last year of his contract and Real Madrid bought him for 10m euros. So, I think Vidal's transfer fee should be in that range, 10-12m euros, not more.
