The DoF system works extremely well in the majority of clubs in Europe.Rome burned while DOF fiddled - we never ever had DOF - that was turning point a position made by an accountant owner who knew nothing about football - from then on money poured down the grid from Koeman onwards...... That position of DOF was the death knoll of 100 of millions on poor players on lucrative contracts with no sale on fee !!!
IF used correctly it prevents many of the issues we have faced over the last few years.
The DoFs have not been the issue here, a overbearing owner and a useless Chairmen sticking their noses in things have been our major issues.
Not a single Trophy was won in Europe last season by a team that doesnt employ the DoF system.
