"I've told him to be mentally prepared. Balwant Singh has a slight niggle so I've told him to be mentally ready. He signed yesterday only and had a good practice today," Sen said hinting that Jeje may play up front alongside Cornell Glen.
The Mizoram-born Indian forward has been in sublime form winning three titles -- I-League, ISL for Chennaiyin and SAFF Cup -- in last eight months.
"We now have more options. But still there's some time for the derby. We're not thinking too far ahead. Our focus is to win tomorrow as a loss would certainly be a setback ahead of the big match."
Mohun Bagan began their title defence with a 3-1 win against debutants Aizawl FC.
"It would be good to post another win but it's not easy. The key is to keep on the winning momentum. We will look to create chances.
"Salgaocar FC are a tough opponents. Last season we had an unbeaten record -- draw (away), win (home) -- against them. They have some big names in their roster we have to play really well as a team."
He further said U-20 recruit Azharuddin Mallick is slated to get a start in the left wing.
Salgaocar coach Malky Thomson said they don't have any specific plan for Glenn.
"We will look to return to winning ways after our (1-2) loss to Bengaluru FC.
