Indian cricket has found a good all-rounder in the middle order. I think he can actually fill in the place of Jadeja who was also a good player.
Yuvraj is new to the international cricket and there is a lot more for him to learn. People have started treating him as a star just after 2 good innings, but what I feel is he needs to be given more time and needs experience to flourish as a class all-rounder. This guy is a brilliant fielder, and that is one area where India has always lacked, now inclusion of guys like Yuvraj will change the Indian fielding attitude.
Yuvraj has got success very early in his career so he should not get carried away with the success and fame, instead he should concentrate on his game and try to improve it to the maximum, because after his successful tour of Kenya he has not performed up to his mark and abilities, he should give more consistent performance which is what a job of middle order batsman is.
Lets hope he proves to be an Indian Michael Bevan.
