Having just 12 points in as many matches, the bottom-placed side is virtually out of contention for a semi-final berth after a string of lacklustre performances.
Mumbai's chances are hanging by the thread as they have to win both their remaining matches (including the game against ATK) and further their hopes to qualify would also depend a lot on ifs and buts.
The hapless side has been plagued with injuries to its strikers, which hasn't helped their cause.
The attack looks toothless without French import Nicolas Anelka and Brazilian Andre Moritz. Anelka had missed the last three ties due to a groin injury and it remains to be seen whether the star player will be risked in the all important clash tomorrow.

Hat-trick scorer Moritz had sustained a hamstring injury against Chennaiyin FC in the last home game and is unlikely to be fit.
Indian forwards Subash Singh and Abhishek Yadav, who have a goal each to their credit, would have to pull up their socks and pump in goals to harbour any hopes of qualifying for the play-offs. Subash has been guilty of squandering chances and the hosts would hope he comes good and converts the chances in the penultimate league clash.
