The Blues, who lead Group E with two wins from as many games, made the arduous trip to Shillong over the weekend where they beat Lajong 2-0 in the I-League and Albert Roca said his side will have their work cut out against Abahani.
"The schedules haven't made things easy for us but we've never been a team that moans. We're hoping to handle this situation as well as we can. The new format of the AFC Cup doesn't allow us the luxury of even one bad game, so we're going to have to put everything behind us and get the job done."
Bengaluru's suspension woes don't end with the Spaniard as midfielder Cameron Watson and defender Sandesh Jhingan too will sit out of the game after having picked two cautions each.
"Cameron and Sandesh are vital players and will be missed, but we have a squad that's capable of stepping up when the need arises," said Roca, adding that a call on goalkeeper Amrinder Singh's availability will be a late one.
Abahani haven't had the best of starts to what is their debut AFC Cup campaign, going down 2-0 to Maziya at home and 3-1 to Mohun Bagan in Kolkata.
Interestingly, Abahani coach Drago Mamic has an Indian connect in that he was coach of I-League side Churchill Brothers in the 2010-11 season.
