ATK were thrashed 0-3 by Chennaiyin FC last season in the first leg semi-final, something that led to their ouster in 2015.
Having learnt their lessons the hard way, ATK's South African midfielder Sameehg Doutie said they're focussed on a winning start and hoped they would have the advantage to start the semifinal leg at home.
Table toppers Mumbai City FC, on the other hand, qualified for the semi-finals for the first time in three seasons after they outclassed defending champions Chennaiyin FC 2-0.
"We are ready to give it all. We are playing at home so we must make the most of it," he said.

Their only loss at home this season had come against the same team Mumbai City FC who won via a 79th minute Diego Forlan goal in the league fixture on October 25.
Their record at the adopted Rabindra Sarobar Stadium has been poor with only one win (against Delhi Dynamos FC) from seven matches but Doutie said it did not matter.
"We have depth in the squad which has helped us till here. We believe in ourselves. Despite playing so many draws, we are the only team to have made semifinals in all three editions," Doutie, who will make a comeback after recovering from fever, added.
