Though Dahiya backed Gambhir to come good later in the tournament, he conceded that the left-hander not scoring runs is a worry for the team.
"If you ask me, Gautam is our best batsman and there are no two ways about it that if your best batsman is not in form, it is a problem for the team," said Dahiya before Knight Riders' final game in the UAE against Rajasthan Royals.
Gambhir has had a disastrous run scoring 0, 0, 0, 1 in the first four games.
In fact, the Delhi batsman batted at number three after a streak of ducks at the top of the order but Dahiya reckoned it would be best for the team if Gambhir bats at his usual position.
Asked about another out of form batsman Yusuf Pathan, Dahiya said: "You cannot deny the fact that he (Pathan) is not among runs and that is a big concern, for him and the team management. Let's see if things improve in the next couple of games."
Dahiya concluded on a positive note, saying the bowling line-up comprising Morne Morkel and Sunil Narine will help Knight Riders progress in the tournament they won in 2012.
