Kolkata, Nov 4 (IANS): Atletico de Kolkata (ATK) are not unduly worried at the prospect of bracing up against former coach Antonio Habas in their Indian Super League (ISL) football match against FC Pune City, goalkeeper Debjit Mazumdar said on Friday.

Debjit said the team hasn't spoken about Habas as they gear up to take on their former coach's new team Pune away on Sunday.

Habas led ATK to the ISL title in its maiden edition in 2014, following it up with a semi-final finish in the next season. The Spaniard then left ATK for Pune this season allowing fellow countryman Jose Molina to take over the reins.

With Pune though, Habas has not tasted the same success with the side languishing at the bottom spot of the eight team tournament with just one win from seven matches.

"We are playing against Pune and not Habas. There has been no mention of him in particular in the dressing room. We are concentrating on our own game," Debjit told reporters here on Friday.

ATK are top of the heap after seven matches with 12 points in their kitty. Though ATK haven't played great with three wins and three draws, their victory against NorthEast United FC in the last game in Guwahati was commendable.

Marquee player Helder Postiga shrugged off injury concerns to inspire ATK to a 2-1 win afer trailing 0-1 in the first half. The Portuguese scored one and assisted another goal in a sterling second half display.

Debjit said NorthEast's win was their best game yet.

"That was the best game we have played so far. The manner of the win gave us a lot of confidence."

The in-form goalkeeper said that staying top of the table is not as important in the ISL as finishing in the top four is.

"Our aim is to make the semi-finals. That's what matters here. Staying top is not the aim. Of course it's the best place to be, but our aim is to be in the playoffs," Debjit who has made a string of acrobatic saves in a few matches, said.

Asked what has been his most memorable save till now, Debjit picked the one where he denied Mumbai City FC's winger Sony Norde at the Rabindra Sarovar Stadium.

"I think that's a save I like. This season has been good for me so far and my confidence level has gone up considerably from last year," Debjit, who has made 15 saves in the tournament so far, said.
