What do you think mate,sehwag himself is happy with his own present performance. iam sure every time he goes to bat he thinks that it will be his come back. And people sitting and watching him thinks the same. But unfortunately it is not happening. But that doesnt mean that he should feel ashamed of. He is not involved in any match fixing or anything like that for he feel ashamed of. Forget about dropping him from the squad but think about playing him on and off so that he reads the opposition and at the same time we may get new player when Sehwag is not playing one or two matches. But dropping him off is something should not be recommended.
