Churchill Brothers, with 39 points from 18 matches, are one point behind league toppers East Bengal who have played two more matches than them.
While Air India, who are fighting relegation, are placed 12th with 18 points from as many matches.
The long break has helped Churchill Brothers playmaker Roberto Silva to completely recover from his finger injury and coach Mariano Dias will have a full squad to choose from for tomorrow's game.
"Air India is fighting to come out of relegation and will come hard on us. We have to be on guard and play to our potential and win tomorrow to keep ourselves focused on the way to win the title," Mariano said.
