India have won nine international matches on the trot, including an unofficial game against Bhutan.
Constantine's past pupils who were part of the Indian team for the 2011 Asian Cup in Doha, joined in the applause.
"The 2011 Asian Cup was a huge learning experience for us. This present team is on a roll and are very close to repeating the feat. Make it count," ace defender Mondal said.
"Constantine has brought in a fighting spirit into the team and that provide our boys with a cutting edge over their opponents," he added.

"It rightly reflects how well-tuned they are at the moment. Right from the coach to the players, everyone is operating together as a team."
Mondal's central defence partner Mahesh Gawli also sounded exuberant.
"As former footballers, we look for an upward graph of our national team. I'm really happy that they are doing well. I wish all the best for their forthcoming match against Macau," he said.
