ATK would do well to remember their last clash against Chennai, where they had failed to close out despite taking a lead in a match during which their influential midfielder Jofre Mateu was harshly booked.
But there's good news for ATK as the Spaniard will be returning against Chennaiyin FC whose defence would be depleted without the trio of Bernard Mendy, Jairo Andres Suarez and Abhishek Das.
The Frenchman had scored a stunning bicycle kick in their 2-1 win over Kerala Blasters and ATK's full strength side would look to go for an all out attack after Chennaiyin's star Brazilian forward Elano Blumber scored from a penalty deep into the second-half injury time.
One of the concerns for ATK is there tendency to concede goals despite taking the lead, something that has happened in three games. They are, in fact, yet to win a game at the home venue of Vivekananda Yuva Bharati Krirangan since their 3-0 rout of Mumbai City FC in the ISL kickoff on October 12.
Ahead of Chennaiyin FC by virtue of goal difference, ATK cannot afford to lose as it would see them drop down the table for the first time in the league.
