Delhi Capitals head coach Ricky Ponting on Thursday said that pacer Ishant Sharma is suffering from a heel niggle and the side is working on his faster recovery. “He has been ultra-impressive, pretty much from the first day we arrived here for the training camp. Physically he looks a little bit better, he lost a little bit of weight from last season. He is definitely fitter and bowling faster. His lines and lengths and slower ball execution are excellent so far,” Ricky Ponting said while replying to an ANI query in the virtual post-match press conference.
