The short answer is NO. There won't be any City fans who will think this is tainted because of their FFP cheating.
Fans from other clubs will, definitely. In fact I was in my local supermarket Friday and bumped into a woman wearing a West Ham top (the morning after their Euro victory) the convo went like this, word for word.
Me: "you must be happy this morning, great win last night....I don't support West Ham, I'm a Man Utd fan, but I was happy the Hammers won, great result..."
Her: "..ah thanks very much, yeah I'm still hoarse this morning from all the shouting! It was so good though, such a great night...so you're Man Utd then? I was rooting for you on Saturday (FA Cup)...shame eh.. "
Me: "yeah I am...I know, I was hoping we'd beat them, but how can you compete with City when they have 2 world class players in every position?!"
Her: "...yeah but they have 2 world class players because they're cheating! If we overspent, West Ham would have 2 world class players in every position!"
At this point Her husband comes round the corner. Conversation carries on...
Him: "..they don't have the toothpaste love..."
Her: " ok..(points to me) we were just talking about last night...he supports Man Utd.."
Him:.."oh do ya?...I'm Spurs...season ticket holder.."
Me:.."..oh Spurs...sorry to hear that mate (we all start laughing)...no actually my brothers a season ticket holder...I bet you two have a few clashes now and then being West Ham and Spurs (laughing)..."
Him.." (laughing)..yeah we do, it's all good fun though...shame about the FA Cup Saturday for your lot, did you go?"
Her: "..yeah we were just talking about the FA Cup.."
Me: "..no I didn't go, couldn't get a ticket but yeah, bloody annoying we lost, especially to them..."
Him: "...yeah but those c*nts have been cheating for years! Look at all the FFP stuff going on, I bet nothing happens with that, they'll get away with it...absolute joke" (He actually started getting pretty animated at this point)
Her: "I just mentioned that..."
Me: "..yeah exactly...what can you do...anyway, I had better leave you to it, nice meeting you both...cheers"
Them: "you too mate...take care"
And just the other day, I get a WhatsApp from my mate, he's an Arsenal supporter.
Him:.."hello mate, how you doing? I watched the FA Cup, was really hoping your boys would beat them..."
Me: "I'm good mate, hope you are too. Yeah me and you both, but what can you do. We just don't have the squad depth that City do, they've got £70m sitting on the bench!"
Him: "I know it's ridiculous, but then if we (Arsenal) cooked the books like they've done we'd have quality sitting on the bench too. 115 FFP actions and f*ck all will get done about it..."
Me: "don't get me started on that mate.."
The moral of this story is that the first thing that came out of all their mouths seperately, when mentioning City, was the fact they all mentioned City were cheats. I didn't even have to say or goad them at all.
Every other fan of every other clubs knows it.
