Durban: Bangalore's loss on Friday against the South Australia Redbacks has given the Mumbai Indians a ray of hope to qualify for the semi-finals of the Champions League T20 and turned their game against fellow IPL side on Sunday into a virtual quarter-final clash.

With one win from three games and the last league outing on Sunday, Mumbai know that they must win this game to keep their hopes alive of making it to the last four. It definitely helps that they have a positive net run rate and a big win will only help them as the photo-finish in the race to the second semi-final spot hots up in this group and will in all probability be decided by decimals.

The Lions, who are placed fourth in the group, will eye a win against Guyana in the first game of the day. A win will put them on four points and also put them within striking distance of a semi-final berth with one game left to play. Bangalore too have two games left, but the team management will surely like to register two straight wins to wrap up a semi-final spot without any more hiccups.

Only Mumbai have Sunday's game to play and therefore, cannot afford to lose the plot now. They have paid for the price of batting and bowling inconsistently and have been stunned by less-fancied sides in two games.

The Sachin Tendulkar-led side had promised a lot with their impressive IPL season but have just failed to click as a unit here.

Except for Sri Lankan pacer Lasith Malinga, who has bagged six wickets by conceding 83 runs in the three matches, none of the Mumbai Indians bowlers have made a mark and that has been the main reason for their tough times in this tournament.

Zaheer Khan and Harbhajan Singh have been disappointing so far. Zaheer has taken just one wicket having conceded 105 runs in the three matches, while Harbhajan has scalped two at the expense of 86 runs.

On the other hand, Royal Challengers Bangalore began the tournament with an easy nine-wicket win over Guyana with South African Jacques Kallis starring with the bat and ball. They, however, were brought down to earth with a humiliating eight-wicket loss to South Australia Redbacks on Friday.

Without Kallis, the Anil Kumble-led side failed in both batting and bowling as they were shot out for 154 and then none of their bowlers, including the captain himself and South African Dale Steyn, making much impact against the Australian side.

The two teams shape up equally on paper. It's Tendulkar's genius vs Kumble's determination, but one still feels that Bangalore will have an edge in this battle of the giants.

Durban: Royal Challenger Bangalore skipper Anil Kumble on Friday held his team's batting failure for the humiliating eight-wicket defeat to South Australia in the Champions League Twenty20 Group B match here.

"Too many wickets at regular intervals, especially losing (Ross) Taylor at that stage. Dillon (du Preez) got us to 150, we could have put pressure if we got early wickets," a disappointed Kumble said after the match.

"We could have bowled better, but should have had 15 runs more," he added.

Preez and Taylor scored an identical 46 to help Bangalore overcome a mid-innings slump and post 154 although it later proved insufficient.

Kumble also admitted that they missed South African all-rounder Jacques Kallis' service on Friday and hoped he will be available for the next match in the tournament.

"The next game is a must-win for us. Hopefully Kallis will be fit for the game," he said.

RCB now takes on another IPL side Mumbai Indians on September 19 here.

Meanwhile, South Australia captain Michael Klinger, who was adjudged man-of-the-match, was satisfied with the team's performance.

"This is really good all-round performance. We have got the talent to beat anyone and the boys are believing in it at the moment. Great atmosphere in the dressing room, this is fantastic," he said.

"(Shaun) Tait is a fantastic weapon for us. Daniel Christian is one of the best in the death," he added.

The captain also said that they have put much effort to improve the fielding of the team.

"We have put a lot of efforts in fielding and we are getting the results," said Klinger, who made an unconquered 69 off 57 balls with the help of nine fours and a six.
