IPL 2017: Can Mumbai Indians tide over starting problems?

Mumbai Indians
SQUAD: Rohit Sharma (Captain), Jos Buttler (wk), Parthiv Patel (wk), Nicholas Pooran (wk), Krishnappa Gowtham, Ambati Rayudu (wk), Lendl Simmons, Kulwant Khejroliya, Karn Sharma, Saurabh Tiwary, Asela Gunaratne, Mitchell Johnson, Harbhajan Singh, Mitchell McClenaghan, Shreyas Gopal, Siddhesh Lad, Vinay Kumar, Kieron Pollard, Krunal Pandya, Tim Southee, Lasith Malinga, Jagadeesha Suchith, Nitish Rana, Hardik Pandya, Jasprit Bumrah, Jitesh Sharma, Deepak Punia.
INS: Mitchell Johnson, Saurabh Tiwary, Karn Sharma, Asela Gunaratne, Krishnappa Gowtham, Kulwant Khejroliya, Nicolas Pooran.
OUT: Guptill, Corey Anderson, Marchant de Lange, Unmukt Chand, Akshay Wakhare, Nathu Singh, Kishore Kamath and Jerome Taylor
AVAILABILITY: The good news for Mumbai is that their skipper Rohit Sharma, who was on a long injury layoff since October, is back and will definitely be key to their success. Apart from Rohit, there are no real injury scares though Lasith Malinga and compatriot Asela Gunaratne are due, to miss the opener against Rising Pune Supergiant due to national commitments.
STRENGTHS: MI have found a good balance to their side as they bought smartly in the auctions. They've retained 20 players from the previous squad. They've got back one of their heroes in the victorious 2013 campaign, retired Aussie tearaway Mitchell Johnson who had a productive Big Bash for Perth Scorchers. They have also got back Saurabh Tiwary after four years. Mumbai have always been a batting heavy team. They have Rohit Sharma and Lendl Simmons and big hitting all-rounder Pollard. They also have the dependable Rayudu and explosive opener Lendl Simmons, who can turn the game around. Their bowling department too is no less with the likes of Malinga, Johnson, Harbhajan and Bumrah.
WEAKNESSES: Mumbai have the reputation of being slow starters and they clearly, need improvement in this area. They are also over-reliant on the likes of Rohit and Pollard.
