Bharat FC are currently 10th on the 11-team table, having garnered 5 points from 6 games while their winless Goan opponents occupy the last spot with 3 points from 7 games.
A victory for the League debutants would help them inch their way up the table, but a loss would confine them to the relegation zone currently occupied by Sporting.
Bharat FC seemed to have hit the groove after an upset 2-0 victory - their first win - over Goan heavyweights Salgaocar, but then a following defeat by an identical score against Mumbai FC halted their upward movement.
Watkiss said that he expected his team to dust off the defeat against Mumbai and focus on the job at hand.

"We all know we did not play well against Mumbai FC. However, we cannot let that burden our minds. We know that we have got enough in the tank to get good results at home and I have told the lads just that. We have worked on a few things in training and I am hopeful that we can execute these things on the pitch on Wednesday night," he said.
Coach Watkiss said that the trio's return will give his side a welcome boost.
"Bobby (Hassell), Vignesh and Ravanan are good players and play important roles in the team. The guys who stepped in for them during the last match have done a good job, but I am happy that I will again have a full strength squad to choose from.
