Already regarded as the world's richest and most successful Twenty20 cricket team, the <a href="https://www.cricketcountry.com/tag/mumbai-indians">Mumbai Indians</a> will now attempt to underline their status by claiming their first back-to-back titles in the <a href="https://www.cricketcountry.com/tag/ipl">Indian Premier League</a>. <p></p> <p></p>Led by senior Indian batsman <a href="https://www.cricketcountry.com/players/rohit-sharma/">Rohit Sharma</a> and owned by Nita Ambani -- wife of India's richest man, Reliance Industries billionaire Mukesh Ambani -- Mumbai have won an unsurpassed four IPL titles. <p></p> <p></p>So far they have been unable to match the Chennai Super Kings' feat of 2010 and 2011 by winning the world's most lucrative T20 league twice in a row. <p></p> <p></p>But Mumbai, who open the coronavirus-delayed IPL season against the Super Kings in Abu Dhabi on Saturday, head into the tournament as the bookies' favourites for a fifth trophy. <p></p> <p></p>Mumbai's financial clout is formidable. Ambani, who bought the franchise for more than $100 million in 2008, has been rated by Forbes as the world's second richest sports team owner behind former Microsoft chief executive Steve Ballmer, who owns the Los Angeles Clippers. <p></p> <p></p>According to an <em>Economic Times</em> estimate, the Indians are worth $115 million, the highest among the eight IPL franchises. <p></p> <p></p>The team has an impeccable playing pedigree too. Their founding captain was the now retired Sachin Tendulkar, the record-breaking batsman who is worshipped by Indian fans. Former Australia captain Ricky Ponting is another ex-skipper. <p></p> <p></p><strong>'Absolute greats' </strong> <p></p> <p></p>But it was only when Sharma was appointed captain in 2013, after Ponting stepped down due to loss of form, that the team became a force to be reckoned with. <p></p> <p></p>The 33-year-old star batsman has led by example, scoring 3,728 runs since joining Mumbai in 2011 and captaining the team to IPL trophies in 2013, 2015, 2017 and 2019. <p></p> <p></p>Sri Lankan legend Mahela Jayawardene is the coach, while West Indian big-hitter Kieron Pollard and India quick Jasprit Bumrah add power to the team. <p></p> <p></p>Australia paceman Nathan Coulter-Nile, part of the Indians' first title win in 2013, returns this season after being snapped up for $1.12 million in the December auctions. <p></p> <p></p>"It's good to come back to the most successful T20 franchise of the world," said Coulter-Nile. "Obviously the team I was involved with then was filled with absolute greats. Ricky Ponting, Sachin Tendulkar, Harbhajan Singh, Rohit Sharma." <p></p> <p></p>"And to come back to see this team now developing those sort of greats again. Rohit Sharma is a great in himself. Bumrah, best death bowler in the world." <p></p> <p></p>However, the loss of pace ace Lasith Malinga earlier this month was a big blow, after the veteran Sri Lankan opted out of the tournament to be with his family. <p></p> <p></p>But despite the loss of Malinga, the IPL's highest wicket-taker with 170 scalps in 122 matches, Mumbai's fans still expect their team to come home with the trophy.
