How is it that Federer had so many aces against Agassi but doesn't use aces against Nadal ?

A major reason Federer can Ace Agassi more often than he can Nadal is that Nadal is much faster on court.  You are talking about placement and speed of the ball and if you hit the outside corner on Agassi you may get it by him, but because Nadal is faster, he has more opportunity to get to the ball.  This is much the same reason Federer has problems beating Nadal on clay.  Clay is a much slower surface and Nadal's speed matched with the speed (slowness) of the ball makes it a much better surface for Nadal than Federer.

Chalk another one up for Nadal. There are some other decent players left in the tournament, but noone who's likely to threaten Nadal.

Its going to be a tough competition between Nadal n Federer. But looking at the superb form of Nadal, I think Nadal might pull off his 2nd Grand SLam title too considering Federer has never gone past the Quarter finals of French Open.

Nadal is actually right handed, but he trained to hit left.  I think he likes a two handed forehand, which is his backhand.

Of the 2, it's still Sampras. Federer has done some amazing things.- 24 straight wins in finals, longest hard-court winning streak, 7 Slam titles so far. He's also possibly the most gifted player in history. He can routinely hit shots that noone else ever tries. He can play offense and defense equally well. \nEven so, if you look at what Pete acheived (14 Slams, #1 for six straight years, the competition he faced), it's hard to argue that Federer is better. In a few years he may well be, but he'll need to win a few more Majors first.

My guess must be FED EX he's an overall player able to play in any surface to perfection, better place your bets on Roger Federer.

Agassi is alive and well. He was injured for a while and was not seen on any courts. He is back healthy and playing in Wimbledon. He will retire after the US Open. Go Andre!!!

nadal was very very lucky to beat Federer on hard court and he'll have to have all the good luck available in the universe to beat him on grass.\nbut he is good on clay and I'll give him the credit for beating Federer here.but Federer is fast improving on clay also and I'll love to see him defeat Nadal in the final of French Open.

Tu as oublié la défaite de la finale de Roland Garros contre Nadal, échec en 4 sets après le gain de la première manche 6/1!!!\nMais moi, je pense qu'il est quasiment impossible de ne pas perdre du tout sur une saison... Federer est clairement sur une autre planète, c'est un génie du jeu, et déjà un des plus grands (sinon le plus grand) joueurs de l'Histoire!!! L'an dernier, il n'a perdu que 4 matches sur 85, mais contre 4 joueurs différents... Safin, Gasquet, Nadal et Nalbandian; ce qui prouve bien que, sur un match, il peut être prenable!!!\nMais c'est un monstre absolue qui va battre absolument tous les records du tennis, alors quelque part, je pense qu'il en est capable... de là à ce au'il le fasse vraiment, je pense malgré tout qu'il y a encore de la marge!!!

Nadal does make Federer work very hard. But that's what Roger has lacked, good competition. I think it will improve his game as such. You must fall into a rut when you don't have opposition that challenges and pushes you to stay at your best. You are only as good as your competition and it's good that he now has some. I think Roger will be grateful for Nadal and will rise to the challenge. It's good for tennis.  But overall Federer is one of the most talented players I think I will ever have the pleasure to witness. So I will say Federer.

For now, I would say Sampras because he did it for longer.  They both can play various styles but within that variety,  I'd say Sampras was more of a classic power player and Federer the more "artistic", touch player.\n\nWhen it's all said and done, and if Federer has a few more dominant years, I think that most people will answer your question with "Federer".  I'm definitely pulling for him to break Sampras' record for most majors won in a career.

I think this is Federer's turn to finally beat Nadal on clay because his reign of however many consecutive wins is up.  Believe me, I'm not taking anything from the youngster because he's damn good but I think this is Federer's French open.  Maybe I'm just thinking ahead.

I think Federer is a great tennis player, but it must take a long time before he can be  as good and as famous as Agassi and Pete Sampras!

i totally agree.\nNadal is Hoooooooooooottttttttttttttttttttttttttttttt!\nHe may not be dominating the grass and hard courts but, he is definately the king of the clay. with a little more practice Nadal will be the King of all surfaces.\nNadal is the best!!!!!!!!!!!!!

because Nadal is an expert on clay court not like Federer who is only best on grass and hard court

Well...Nadal and Federer have played each other 4 times in ATP tournaments and Nadal has won 3 of these matches.\n\nNadal was even able to beat Federer when he had only just recovered from his foot injury so if he is healthy he probably will beat Federer.

it is there style of play. clay bounces high and slowly, which suits nadal because he plays with loads of topspin so the ball kicks up even higher on clay. also clay is a slow surface, so the points are longer, which he loves because his fitness is so good. federer is so good on grass because the ball stays low, which helps his one handed backhand. also the ball skids low so when he hits a slice its very difficult to deal with. grass is also a fast service so federers medium speed serve and big forehand are very effective. nadal has less power and more spin on his shot so its more effective on grass
