Mumbai: Indian off-spinner Harbhajan Singh has said that he is going to use the off-season to concentrate on mental and physical rebuilding."I'm going to be training. I haven't been bowling much. I had a side strain, but I'm much better now. I'll start bowling soon," said Bhajji. "I'm going to just be working on getting back to match fitness and probably play some matches for my team Indian Airlines," he added.Demoralizing lossThe Turbanator said the loss against Pakistan was demoralizing, but the upcoming triangular series in Sri Lanka is going to provide new opportunities and a chance to put the disappointments of last season behind."Of course you play badly, you also learn. So, we'll see what went wrong and we have to work together in the new season, with a new coach, towards new goals," he said."We will try to work around the problems of last season, especially since all the players will be fresh from the three-month break," the off-spinner said.The ICC is still looking into his action. Harbhajan refused to comment on the status of the investigation and until he hears otherwise, he plans to keep on playing cricket.
