Rahul Dravid has no concerns over KL Rahul's lack of T20 World Cup runs as India prepare to face Bangladesh.

Opening batter Rahul has failed to reach double figures in his three innings after making a half-century in a warm-up game against Australia.

Rahul fell for nine as India were beaten by South Africa, but head coach Dravid has backed the 30-year-old to show his class ahead of a clash with the Tigers at Adelaide Oval on Wednesday.

Asked if he has concerns over Rahul's technique, Dravid replied: "No, not at all. I think he's a fantastic player and he's got a proven track record.

"He's done really well. I thought he's been batting superbly. These things can happen in a T20 game sometimes.

"It's been a tough - it's not been that easy for the sort of top order batsmen. This tournament has been pretty challenging.

"I thought he was superb in the practice game against Australia with Mitchell Starc and Pat Cummins. It was a pretty good attack, and I thought he batted superbly that day. So he's actually playing really well.

"Just hoping it all clicks together over the next three or four games. We know his quality, we know his ability, and he's really well suited for these kind of conditions, these kind of pitches.

"He's got a good all-around game. He's got a very good strong back-foot game which is obviously very much required in these conditions. We're pretty confident and happy with the way he's hitting it."

India are second in Group 2, level on points with Bangladesh and one behind the Proteas.
