Is it not all about the result?
I've renewed my st for years before Vicente even considered coming here, never has an individual player "made" me renew.
As good as his derby performance was I could most probably show you half a dozen other appearances where he was a passenger and offered...
I don't know what "proof" you want tbh, and as it's an opinion I neither need or want to prove anything to you or anyone else.
I never said he wasn't a good player I said he was a bad signing, there is a difference.
