The bottom placed neighbors go head to head with a hope of a top 4 finish.
The derby may well make or break either side's campaign. Mathematically both of them have a chance of a top 4 finish. It all boils down to who wants it more.
Key Battle
Kostas Katsouranis vs Jan Štohanzl
Koatas has single handedly carried Pune on his shoulders. The common game plan is to stop the Greek in order to stop Pune. He will be up against a bulky Jan Stohanzl. Jan has been few bright sparks of Mumbai's rocky campaign.
Elsewhere both teams are as unpredictable as weather in topical islands.
Players to watch
Pune
Dudu - The Nigerian has been very good for the Western outfit providing a presence in the box as well a target to hit on.
Mumbai
Subrata Pal - The Mohun Bagan keeper has been brilliant one day and pedestrian the other. Tonight he needs to be at his very best if Mumbai harbour any dreams of semis.
