I think both the Aus and US opens were on grass, with France being the odd one out, as that's always been on clay.

As for the greatest, I'm another who still thinks it's Laver, because of the amount of slams he missed due to turning pro.

lol

there is no debate

federe has won more grand slams therefore he is the best.

He hasn't finished yet either

It's conjecture. Laver doesn't have the slam titles, federer does.

laver won the grand slam in the same year . the only player ever in history . plus his an aussie

Laver didn't win 15 grand slam titles(and counting). Holy god that's alot.

Federer doesn't have the grand slam, Laver does. Twice. Winning the grand slam is the ultimate achievement as a tennis player, so does that mean his achievements out-score Federer's greater number of wins at the majors?

Using just 1 measurement can lead to faulty results, when other data is available.

Of course it's all conjecture and at the end of the day it's down to personal opinion.

You might want to ask Don Budge about Laver being the only player to do that.

Who to believe? Lord Percy or fredie? Tough choice.

Surprisingly fredie, Don Budge was not an Aussie but American, and did the Grand Slam in the 1930's.

Please find enclosed your backside. Again.

laver didn't win 15 grand smal titles.

Federer has won more
