True. Fed has warmed up a lot to Nole lately, he has found a new respect for him maybe because he now sees him as a very dangerous threat. Also it's been a long time these two are tied at the top, so yes definitely they are friendly and respectful of each other. I like that.
By the way, these round collar shirts shape up Nole's body nicely. It's a shame he cannot dress like that for official matches. His hotness factor would be over the roof.
