Hall of Fame
I agree, Djokovic is the "best" loser out there, always very friendly, whether he wins or loses.Im a big fed fan, he is my hero, but after the match yesterday and the one in paris it just bothers me the way he thanks his opponents when loosing. Yesterday and the match after paris he has been cold towards nole. When he wins he wants too hug and kiss all day long. Nadal is exactly the same to. Bad sportsman in that kind of way.
Djokovic is the only one acting the same when loosing and winning, always congratulates at the net and is very friendly.
Feder in general seems to be a sore loser, but he can be very friendly after he loses. In his press conference afterwards, he mostly is a little more honest and can reflect on the loss, generally giving his opponent the credit.
Nadal -I think- is a little more friendly in his handshake after a loss, but he can be quite cold sometimes. But when he loses, he tends to be a bit negative about his opponent.
I guess Djokovic is the best loser of the three. he seems to have this sportsmanship notion about him, like when you watch a tennis video of the 60's where the loser always seemed to run towards the net to congratulate the winner in a warming way.
