You got me there, I just did a trawl on their transfers, they have actually spent a fair bit but they have had to sell their prized assests to spend. That 11m was a stat that was mentioned on Sky either I took it up wrong or they got their stats wrong.
Last season they sold Rodwelll for 15m
Season before Arteta for 10m and Beckford for 4m
09/10 they sold lescott for 22m
Everton are a club that can not afford to turn down offers for their best players and in all fairness Moyes has done an incredible job considering he has had to sell his best players every season almost!
