there is a saying in indian subcontinent that once a person becomes so famous, that other people becomes jealous of his success, that this jealousy curses the person good luck and turns his good luck into bad luck
now let apply this theory to federer up and down career
after reaching 10 consecutive grand slam finals from 2005 Wimbleodn to 2007 US Open, he was first stuck by mono disease which ended his 10 consecutive final steak when djokovic defeated him in straight sets in AO 2008.
in his next grand slam final FO 2008, he was humiliated by nadal when he lost the final in straight sets (his only straight sets lose in slam final) and third set score was 0-6 a bagel (again his only 0-6 loss in a grand slam final).
next came wimbledon 2008 final, where he lost his first grass and also non clay grand slam final to nadal in 5 sets
in A0 2009 final, again he lost his first hard court slam final to nadal
then in US Open 2009 he lost to Del potro his first defeat to first time grand slam finalist.
i rest my case, you have the floor
