Sachin has really slowed down during last cuople of years. till 2001-02 He was miles ahead of the others. But now Lara,Ponting,Inzamam,Hayden and Kallis are trying to catch him. Pariculrly lara in no. of runs and Ponting in both no. of runs & centuries.but i am sure that Sachin will come bakc to his peak form in this year. He will play for 5-6 years and will end up with 52-54 test centuries and about 15500-16000 test runs. But watch out for Pinting as age is with him and the way he is scoring and the amount of test cricket Australia plays he can definitely beat Sachin for runs and centuries as well.Lets wait and watch.
