Placed third with 18 points from 12 matches, the inaugural edition champions can secure a top-four finish with a draw but a bigger concern for coach Jose Molina is that they have only been able to get past Delhi Dynamos FC at home this season.
ATK have two more home matches left in the league stage. The Kolkata side will face Pune City FC in their last home match on December 2 and prior to that Molina has made his intentions clear.
ATK incidentally enjoy a superior head-to-head record against both Kerala Blasters and NorthEast United FC, while only one of those team can overtake second placed Delhi Dynamos' points tally as they battle amongst themselves in the concluding league clash.
Based on current form, ATK will be favourites to become the third team to book their place.
ATK scored a last-gasp 2-1 victory against FC Goa in their last match. It was a match they dominated and deserved to score more goals, a fact that was emphasised by the Spanish coach.
"We had a great match in Goa. We could have scored more goals but I think the players now are not bothered about anyone. It doesn't matter which teams is in front of us. It's all the same. We try to dominate the game, defend well and score as many goals as possible," he said.
Down with fever, the South African mideo did not train with the team today, while Lalrindika and Pearson have not yet recovered from injuries.
Kerala Blasters have done well to reach the fourth spot for now after collecting just a point from their first three matches.
A win for Kerala Blasters will take them closer to the semi-final spot, although they will not be guaranteed a top four place as they are dependent on head-to-head record of teams who can reach 21 points like ATK, Delhi Dynamos and NorthEast United FC.
Despite Coppell's confidence, Kerala Blasters will have to remain guarded against the hosts.
Kerala are on a four-match winning streak at home but have failed to impress in away games.
They have not won any of their last three away matches and have conceded 10 goals away from home, a record that is bettered only by bottom-placed teams like Chennaiyin FC (12) and FC Goa (12).
"Three points are important for both teams. Kolkata have been unlucky in few of the games which they have drawn. They have powerful forwards and we will have to be at our best to get anything out of the game," Coppell said.
