i feel mumbai indians should start bowling attack with Harbhajan and Hardik Pandya 2 overs each. then macklen and bumrah 2 overs each, Kunal pandya and kory anderson 2 overs each, even in team in place of butler Guptil should play at No 4, 5 Kunal, 6 Polard , 7 Kory, 8 Harbhajan, 9 Hardik, 10 Bumrah, if they will play with this team definitely will be in top 4 team
