He was great for us but for some reason I just don't have the same affinity for him as I do for other ex players like Ferdinand, Ronnie etc I can't put my finger on why.
Part of it is probably the Harvey Dent theory. You either die a hero or live long enough to see yourself become the villain. The stars should have aligned when Fergie retired, and Rooney should have left in the Summer of ’13.
Also, look at a list of commonly agreed upon club legends, they’re mostly Manchester United supporters. And if they weren’t when they joined the club then they certainly are now. The likes of Cantona, Ferdinand and Solskjaer have incredible goodwill from the fans. It’s because the club changed them, we as supporters changed them. Manchester United left a mark. Hell, even Dimitar Berbatov still swans about in a United club shirt, with a popped-collar and a fat cigar, generally looking hipster cool.
Also, some of our supporters are young enough to have seen more of Moyes/LVG/Mourinho era than the player who shone for Fergie. That feeling of witnessing Rooney’s hattrick against Fenerbahce can never be replicated by watching an MUTV or YouTube edit. Likewise his Euro 2004 introduction. Some supporters currently in their teenage years only ever saw over-the-hill Wayne!
So I’m not dismissing his contributions to our success. He was elite, and arguably (a distant) 3rd behind Fergie and Giggs on a list of our greatest contributers through this Premier League era. Appreciation and affinity aren’t mutually exclusive though. I feel the same way about Rooney as you do. I can acknowledge his work whilst not adoring him the same way I do others who may have contributed less but have shown that we (Manchester United) mean more.
