That is probably why he isnt hated. He isnt a real threat to the big 4 and never was. He has a combined 2 career slam wins over all of them, and the only one he denied anything was Federer in denying him the U.S Open title, when he already had 5 in a row and the slam record at the time anyway.
I would say most hated in order are:
1. Nadal- hated passionately by both Federer and Djokovic fans. Oddly not hated by Murray fans despite that Murray's record vs him is even worse, but Murray's fans dont seem to do the hating thing as much as Federer fans especialy.
2. Djokovic- hated by some Nadal fans, and even some Federer fans.
3. Murray- hated by Federer fans (due to losing head to head for years now, Olympics last year) and even some Djokovic fans.
I think you're right people don't see Del Potro as a real threat but the thing is he's probably right now the only player with the REAL chance to really reach the elite group.
I sense Del Potro has a real lack of SELF CONFIDENCE which needs to helped with a sports psychologist, himself or his DAMN coach!
He's got to realize this is his time he's 25 now and he hasn't reached a grand slam final in over FOUR YEARS that's shocking someone with his talent.
He really needs to take tennis MORE SERIOUSLY and stop being Mr. Nice Guy. Del Potro can learn a lot from Robin Soderling and Ernest Gulbis having a bit
of attitude can help a tennis player it shows those top guys you aren't intimidated by them.
Del Potro isn't disciplined enough, I don't know who his fitness trainer is but he needs a lot of help. Juan Martin is unhealthy he's always so sickly looking he always looks tired and exhausted on the court. He really needs to get physically stronger.
The problem with Del Potro is his attitude he's too happy go lucky kind of guy he doesn't have the KILLER INSTINCT. He's far too friendly with Djokovic after losing the Shanghai final. Why the hell was Del Potro laughing and acting all friendly with Novak?
Could it be because Del Potro doesn't deep down inside believe he belongs with the elite?
Del Potro needs a major attitude adjustment I agree with John McEnroe this is pro tennis big money and points are on the line.
I am not saying Del Potro cannot be civil but STOP please STOP acting so friendly with the other top players.
You don't see the top women acting friendly they can't STAND EACH OTHER.
And that's what makes women's tennis more interesting sometimes is the fact the women are honest, it is a WAR on the court NO TIME FOR FRIENDSHIP!!!
Since Del Potro has won the US OPEN he's gone through a lot such as injuries. The guy is very injury prone. I think Del Potro's problem is he's TOO NICE.
I've said this before, if Del Potro had Robin Soderling''s work ethic and attitude he probably would of won a second grand slam right now.
Soderling has reached TWO slam finals he's the only guy outside the big four to have done that and a lot of it has to do with Robin's attitude.
People attack Soderling saying he's a jerk, but Robin had the right attitude he never felt the top players were superior to him and his hatred for Nadal helped fuel him when he destroyed him in Paris in 2009.
