Do you know him as a person??? Met in a restaurant and he was rude, didnt gave autograph, or beat his child in front of your eyes, parked to disatvantaged people's place, saw him stealing carrot from a greengrocer, kicked his dog in the park??? Or just read something about him in a tabloid?
You cannot find the reason cause you search the wrong place. Just compare our last seasons midfield to one we got now+ how much DP played this season, and how much Trez was injured.
I dont like scapegoats but it makes me angry much more how much we payed for DYO, and how much wage we're giving him for virtually nothing. I dont think any club should pay the third of the money he costed (15m+), just compare this to Trez's situation who is chased by top clubs and offered 20+ millions for him. He scored lots of goals on minimal wage and can be sold for a fortune, while DYO costed more, earned more did virtually nothing and worth about 5 million at maximum.
