What part of his game has Ljubicic improved lately? This streak of results is surprising everyone... maybe even himself too. Anyway, I haven't had chance to watch him, so I was wondering.
Nothing in particular has improved I'd say, he's just risen his game to the level where he is now able to execute his gameplan without making silly errors. And being a great thinker on court makes those gameplans very tough to hit through + serve of course
