This must have happened a while ago, did people really criticize Dinho for us?I think his hatred of Gundogan stems in response to other posters being over zealous in criticism of Fernandinho in the past. Rodri has had similar too.
Aguero and Jesus have a funny little merry-go-'round too, where some people don't like Aguero due to criticism of Jesus and some don't like Jesus due to criticism of Aguero.
I always thought it was like some people didn't think he was exceptional in moments and others arguing saying no he is always amazing. To contrast that with people actually having to defend that Gundogan is actually a good footballer and others saying he is shit lol.
Those are usually the ones I see, if there was extended period of criticism for Dinho then I must have missed it.
The psychology of forum posters I suppose.
