"Last three overs of last match did not go in our favour.
Our batting order needs to be assessed and we have done that.
In Twenty20 game, it is not a major concern for us since we have a very strong batting line up. I back all our batsmen and we will surely put up a much better show tomorrow," Sekar at the pre-match press conference here.
His side has been criticised for frequent changes in the batting order with the likes of Ross Taylor being sent late down the order but Sekar defended the decision.
"In Twenty20, batting order changes frequently. It is not the set order like in Test matches. So, we need to change and in fact every team does it depending on the situations and its demands. Some matches (Chennai captain M S) Dhoni bats at number eight and on occasions he comes at four. That is the order of the day in Twenty20 games.
"It was one of the odd situations that he has gone to number seven because we promoted Pawan Negi to go and get some quick runs, even six-ball 10 or eight-ball 12 and it's fine even if we lose wickets. Ross is capable of going after the bowlers right from the first ball that he faces," he said.
"I always believed that class is permanent and form is temporary. Ross got 21 ball fifty against Royal Challengers in Bangalore. He showed his class there and I think he is in a good space and I think he should fire tomorrow."
Asked about Mahela Jayawardene's batting position, he said, "It depends on the situation and the context demands. We have played him three, four and five in various other matches." .
