The first leg in Colombo finished 0-0 a week back, in what was also Chennaiyin's AFC Cup debut.
The club will be looking after the fans' train journey from Chennai and accommodation in Ahmedabad. A few supporters are scheduled to fly to Ahmedabad, ahead of the big match.
"We are going to have our fans come all the way from Chennai for the big match against Colombo. We will do our best to ensure a memorable performance for them to take back home. It won't be easy against a confident Colombo side, but we will be up for the occasion," said Head Coach John Gregory.
Versatile Australian Chris Herd, who missed the first leg through illness, is expected back in the starting eleven for the crucial second leg. Herd who was in attendance alongside the Chennaiyin gaffer, added, "We are a confident side with qualification to the AFC Cup group stage being the single objective. I look forward to play my part and help the team secure progress."
There is a lot riding on Chennaiyin who are aiming to become the first ISL side to progress to the group stages in their maiden AFC Cup campaign, after having booked a qualifying berth by winning the 2017-18 ISL title.
