Delhi Dynamos FC host Atlético de Kolkata on Matchday 37 of the 2015 Hero Indian Super League (ISL) at the Jawaharlal Nehru Stadium in Delhi on Saturday. Delhi Dynamos FC, who have the strongest defence in the league having conceded just seven goals in eight matches, will be looking for a repeat of their performance earlier this season when they ran away as 1-0 winners against the reigning champions at the Salt Lake Stadium in Kolkata. The defending champions will also be high on confidence after their thrilling win against Kerala Blasters FC in their last match.Form Guide (Last 5 matches)Delhi Dynamos FC so far: W-L-W-D-DAtlético de Kolkata so far: L-L-W-L-WHead-to-Head: Atlético de Kolkata have never beaten Delhi Dynamos FC in the Hero ISL. Last season saw them play out two draws and when they met earlier this season, Delhi beat Kolkata 1-0.John Arne Riise vs Iain HumeJohn Arne Riise has featured in all matches for Delhi this season and is an important part of the league’s meanest defence. Riise’s transition from left-back to a more central role could not have gone much smoother. He has been a consistent performer at the back for the Lions and is an able distributor of the ball, boasting a passing accuracy of 90%.Iain Hume, along with skipper Borja Fernandez, has played every minute of ATK’s campaign so far. His ability to consistently win headers even though he isn’t the biggest on the pitch has left the opponents scratching their heads. Hume possesses a great spring and a clinical right foot. He is a threat both aerially and with the ball at his feet in the opponents’ final-third.Chicao vs Arata IzumiDelhi Dynamos FC’s marquee player-cum-coach Roberto Carlos has chosen fellow countryman Chicao, along with Hans Mulder, to marshal the Lions midfield for the majority of their campaign. Chicao’s all-action style of play from midfield has seen him make 16 tackles this season. The veteran Brazilian has also done his bit to pitch in with a goal or two from time to time having scored from the penalty spot earlier in the season.The loss of Arata Izumi through injury was a major factor in ATK’s slump. Kolkata’s fortune changed with the re-integration of Izumi to Atlético’s playing eleven after injury. Izumi’s two goals in his side’s last outing against Kerala proved to be the difference. The 33-year-old’s fitness will be a major factor in ATK’s bid to retain the Hero ISL trophy.Richard Gadze vs Rino AntoRichard Gadze will be looking to stand up and be counted. The Ghanaian has got bags of pace and is capable of terrifying the most astute of defences. He has already netted thrice for the Lions this season and will be looking to add to his tally as he bids to cement a permanent starting spot in the Delhi line-up.Rino Anto will have to shoulder much of the defensive responsibility against Delhi Dynamos FC. Anto’s composure on the ball has seen him make 25 tackles and complete 98 passes out of dangerous areas in defence for Kolkata.Saturday’s encounter between these two teams promises to be an absolute humdinger of a contest. Delhi Dynamos FC will look to build on their rock solid defence and hope to do the double over ATK as Roberto Carlos’ men look to move a step closer to semi-final qualification. Atlético de Kolkata, meanwhile, will be aware that a win against Delhi will not only see them leapfrog the hosts in the league table but also put them firmly in the driving seat for a semi-final berth.Squads:Atlético de Kolkata: Amrinder Singh, Juan Calatayud, Kunzang Bhutia (Lachungpa), Arnab Mondal, Denzil Franco, Nallappan Mohanraj, Syed Rahim Nabi, Dejan Lekic, José Luis Espinosa Arroyo (Tiri), Rino Anto, Lalchhawnkima, Augustin Fernandes, Sheikh Jewel Raja, Clifford Miranda, Borja Fernández, Ofentse Nato, Jaime Gavilan Martinez, Sameehg Doutie, Arata Izumi, Javier 'Javi' Lara Grande, Valmiro Lopes Rocha, Baljit Sahni, Nadong Bhutia, Hélder Postiga (marquee player), Sushil Kumar Singh, Iain HumeDelhi Dynamos FC: Antonio Doblas Santana, Sanjiban Ghosh, Ishan Debnath, Thokchom Naoba Singh, Prabir Das, Roberto Carlos [marquee], John Arne Riise, Robert Lalthlamuana, Anas Edathodika, Anwar Ali, Anderson Sebastiao Cardoso [Chicao], Shylo Malsawmtluanga [Mama].
