I guess India would look much harder into these two, and its these situations where they could pull up all bits of energy and put up an inspirational performance. It has happened in recent times (Adelaide 2007 vs Australia).
They need to play mendis and murali like just any other bowler. dont give them too much importance, and play the ball on merit. Sachin can do it and so can Dravid, Laxman and to an extent Ganguly. These guys will come back hard next match. But I agree - Sri Lanka are a very good team now with these two spinners. They have a good captain, good batters (Dilshan, Silva, etc) and a lethal bowling attack (Vaas, Malinga, Fernando, Murali, Mendia). WOW!
