Yuvraj Singh's surprise selection in India's World Twenty20 squad may have led to experts raising doubts about his fitness, but the all-rounder on Wednesday sought to put the record straight by announcing that he was physically and mentally strong enough to make a comeback into the international arena.u00a0

"Experts are not watching me. They don't know about my fitness. It's me who knows what's going on. It's me who is feeling it from inside. I know myself better and I am confident enough to do well in the World Cup in Sri Lanka," said Yuvraj on the sidelines of National Sports Awards function at the Rashtrapati Bhawan, here today.
