We really got Ozil on the cheap.
For those not interested to read the contract: We got him for 44 millions Euro in 3 installments, 24M in 2013, 15 in 2014 and 5 in 2015. Should we be in the group stage of Champions League, then we pay Madrid 1M per year, upwards to 6 years. So in total we could pay up to 50M Euro.
