For some reason guga appears to get little mention in this forum despite defeating federer comfortably at the french in 3 sets and also winning in straight sets in indian wells last year. Guga is a top 20 player despite missing the entire grass court swing and suferring with a chronic hip. However after beating ginepri and henman at toronto, he seems to be back to hes best. Unfortunately he was given the strain too play 2 matches on the same day, and narrowly was defeated despite having 2.M.P in second set. Providing guga stays in good physical condition, I am sure can challenge the best on hardcourts. I believe hes backhand and serve are far stronger then federer, but he lacks in one department and that is hes movement is suspect at times due to his hip. I am sure he will be back in the top 10, providing hes physically fit.
