With the former champions Bengaluru FC's three-match winning run halted with a 0-2 defeat in Mumbai, East Bengal, who are separated from the leaders by just one point, will have a golden opportunity to go atop the table.
East Bengal returned to winning ways against newcomers DSK Shivajians but they were not convincing enough in their 1-0 win in the last round.
Their South Korean star forward Do Dong Hyun still struggled to get back into his elements as they relied heavily on the seasoned Nigerian pro Ranty Martins to put them ahead.
There are also a few injury concerns for East Bengal coach Biswajit Bhattacharya with Robert Lalthlamuana, Soumik Dey and Harmanjot Singh Khabra doubtful for the top of the table clash tomorrow.
However, their attacking midfielder Cavin Lobo is fit and will be available for selection while Dempo recruit Narayan Das may come in place of Dey.
Oozing confidence ahead of the crucial fixture, Bhattacharya said: "We saw their loss to Mumbai they have exposed the chinks in their defence and we're confident of bagging three points."
The Blues will bank on their forward duo of C K Vineeth and Kim Sing Yong and it remains to be seen how Bello Rasaq helm the East Bengal defence together.
As for the last season's runners-up Bengaluru, their captain Sunil Chhetri looked tired and had to be substituted after the break against Mumbai FC.
Bengaluru's defence in John Johnson and Curtis Osano too earned criticism in their defeat to Mumbai and the Ashley Westwood side will be under pressure to live up to their reputation.
