Zaheer on why Mumbai Indians are struggling in UAE...

'I think it is just the form-based situation for us, you know the middle-order has not really fired for us in these last three games and that has put a lot of pressure.'

Mumbai Indians' director of cricket operations, Zaheer Khan said the failure of the team's middle-order in its last three IPL matches has put a lot of pressure on the defending champions.

Mumbai went down to Royal Challengers Bangalore to suffer their third defeat in a row in the second leg in the UAE and slip to seventh position in the IPL standings.

"I think the wicket was just fine, you can make out from how the team batting first went and how we started. I think it is just the form-based situation for us, you know the middle-order has not really fired for us in these last three games and that has put a lot of pressure," Zaheer said after the match.

"So losing wickets after getting that kind of start is never going to help you recover," he added.

Glenn Maxwell's brilliant all-round performance and Harshal Patel's hat-trick powered Royal Challengers Bangalore to a thumping 54-run victory.

The former left-arm India pace bowler also praised RCB's hat-trick hero Harshal Patel.

"He has got the hat-trick, so the man should be on the moon. Bowled very well, his slower one is something, which has become a trend for this IPL and he is having a fantastic season," said Zaheer.

He also said that the five-time champions have done it in the past and there is no reason why they cannot do it again.

"Well, we don't have that much time right now, we will have to really get things moving very fast, it is going to be must-win games for us coming up, so it is very important that the team sticks together and brings whatever it takes to win games of cricket.

"I think that hunger is going to be very important, that determination is going to be very important for us going forward and we got to believe it, this team has done it in the past, so there is no reason why we can't do it," said Zaheer.

"The way MI is known in terms of showing dominance and playing cricket, that aggressive nature of cricket, so far we have not seen," he lamented.

According to the former India pacer, Mumbai Indians hasn't been able to get going, playing well only in patches.

"Well, I think, you know, we have not been able to get ourselves going, as simple as it gets. You got to have 40 good overs of cricket, you got to play good cricket throughout those 40 overs, to win games of cricket.

"So, we have been playing well in patches, and not really able to sustain it and that has been the case so far," explained Zaheer, who has 311 Test wickets.

Young leg-spinner Rahul Chahar, who has been selected in India's T20 World Cup squad, hasn't delivered in the first three games in the UAE.

Asked whether his form was a matter of concern, Zaheer quipped, "I mean, if you are just equating it to number of wickets, then you can say that."

Zaheer admitted that when things are tough, at times one doesn't get the rhythm going.

"But I am pretty happy with the way he (Chahar) is bowling, you know the ball coming out of his hand is absolutely fine, it is just that the situation of the game sometimes you are not in that position, so you can look at it that way.

"In terms of confidence, he is right up there, I don't see any issues around that. It is just about having a few tough games," he said.
