Delhi Dynamos FC will be looking for their fourth straight win when they take on Atlético de Kolkata at the Jawaharlal Nehru Stadium in New Delhi on Sunday. The Dynamos of late have been in excellent form, especially at home with 2-0 and 4-1 victories over Kerala Blasters FC and defending champions Chennaiyin FC in their last two matches. With 16 points from nine games, the table-toppers would like to extend that run and get further closer to the semis. Atlético de Kolkata, on the other hand, suffered a 2-1 loss to FC Pune City in their last game and would look to return to winning ways with an eye also on solidifying their position in the top four. Thus the league leaders will battle it out with the 2014 champions in what is set to be a pulsating Hero Indian Super League 2016 encounter.Head-to-head: In Hero ISL 2014, both the games yielded draws with a 1-1 scoreline in Kolkata and 0-0 in New Delhi. In Hero ISL 2015, the Dynamos edged ATK 1-0 away before playing out a 1-1 draw at home. Earlier this season, ATK registered a 1-0 victory at the Rabindra Sarobar Stadium thanks to Iain Hume’s penalty soon after Marcelinho’s miss from the spot for Delhi.Form Guide (last five matches):Delhi Dynamos FC: L-D-W-W-WAtlético de Kolkata: D-W-L-W-LRuben Rocha vs Helder PostigaRuben Rocha has made himself a regular in the Dynamos side on the back of quite a few solid performances. The defensive bedrock has often stopped strikers in their tracks besides blocking out goal-bound efforts with efficiency. His height also makes him a threat in the box during corners.Marquee man Helder Postiga missed a few games initially due to injury but when he came back he immediately helped his team get past NorthEast United FC with a nice header late last month. His creativity and experience are going to stand ATK in good stead against the Lions. The hosts need to watch out for him.Florent Malouda vs Borja FernandezFlorent Malouda has become indispensable for the Delhi team. The marquee man has orchestrated attacks, snatched balls as well as intercepted opposition attempts all over the park. In Delhi’s last game against defending champions Chennaiyin FC, he also got the goals which had eluded him for long, and it’s a no-brainer that he would be hungry for more on Sunday.Borja Fernandez has been the fulcrum of the ATK team since the inception of the league in 2014. The Spaniard’s link-up play, along with his tackling abilities, will be key to thwarting the formidable Delhi forward-line. And trust the ATK captain to deliver when it matters.Kean Lewis vs Arnab MondalKean Lewis has come into his own this season. The 24-year-old has proven his mettle amidst more illustrious names and has shone bright. His pace as well as calm head sets him apart and he has also got the goals to show for his efforts. The Kolkatan backline will have to be alert in view of his current form.Like captain Borja, Arnab Mondal has been an influential player in ATK’s success story. The India international is a leader on the field and his exceptional passing helps in building attacks from the back. Blessed with good height, he is also a threat during set-pieces.Squads:Delhi Dynamos FC: Antonio Doblas Santana, Sanjiban Ghosh, Soram Poirei, Ruben Gonzalez Rocha, David Addy, Ibrahima Niasse, Anas Edathodika, Chinglensana Konsham Singh, Lalchhawnkima, Rupert Nongrum, Souvik Chakraborty, Florent Malouda, Bruno Augusto Pelissari de Lima, Marcos Tebar, Emerson Gomes de Moura, Denson Devadas, Milan Singh, Malsawmzuala, Richard Gadze, Badara Badji, Arjun Tudu, Marcelo Leite Pereira, Kean Lewis, Amoes Do, Alwyn GeorgeAtlético de Kolkata: Shilton Paul, Debjit Majumder, Dani Mallo Castro, Jose Luis Espinosa Tiri Arroyo, Arnab Mondal, Pritam Kotal, Kinshuk Debnath, Prabir Das, Henrique Fonseca Sereno, Keegan Pereira, Robert Lalthlamuana, Borja Fernandez, Ofentse Nato, Javier 'Javi' Lara Grande, Sameehg Doutie, Stephen Pearson, Bikash Jairu, Bikramjit Singh, Lalrindika Ralte, Sheikh Jewel Raja, Abhinash Ruidas, Bidyananda Singh, Helder Postiga, Iain Hume, Juan Belencoso
