New Delhi: Star batsman Rohit Sharma knows that he is in a "very tricky position" but wants to utilise the upcoming Sri Lanka tour and the subsequent tour of South Africa at home to cement his spot in the five-day format.

"I stand in a very tricky position. I definitely want to do well in every Test match I am playing but it's not easy knowing how Test matches are played these days. It's a challenge and I love challenges. The Sri Lanka series and after that we have a lot of series in India. It will be great opportunity for me to go and perform there," Rohit told 'bcci.tv' today.
