One of my work colleague's dad is a Fed fan and hates Andy. He was trying to spout at me that Federer didn't actually want to win the Gold medal recently and his gullible daughter believed him!
I did point out that was the one little bauble missing from his precious collection and despite being No.1 in the world on 3 outings to the Olympics (I believe he's attended 4) that he's not managed to snag the singles medal
For me, some Fed fans need to wise up on the other players too.
I fear some of those who know nothing about tennis think on these lines. My ex said something like oh fed is clever he doesn't try so hard when there's no money involved. Well I put him right in no uncertain terms, like you pointing out that this is the one thing he's not won and he was desparate to do so.
Oh and hate that cap too. I'm so glad Andy doesn't have AM on his cap etc.
