Chennaiyin FC breathed plenty of life into their Hero Indian Super League Season 2 campaign with a 4-1 win against Kerala Blasters, FC but on Tuesday they have their work cut out as they take on one of the top teams this season, Roberto Carlos’ Delhi Dynamos FC. At this stage of the league, the Super Machans can’t afford to lose any of their remaining three matches because that will very much end their semi-final chances. Delhi, on the other hand, will look to displace defending champions Atlético de Kolkata at the top of the table with a win at the Jawaharlal Nehru Stadium in Chennai.Form Guide (Last 5 matches)Chennaiyin FC: D-L-L-L-WDelhi Dynamos FC: W-D-D-D-WHead-to-Head: Delhi Dynamos FC lead 2-0. Last year, they ran away to a 4-1 victory at home before sharing the points in a 2-2 draw in Chennai, and earlier this season they registered a 1-0 win thanks to a Chicao penalty.Bernard Mendy vs Richard GadzeBernard Mendy will have his work cut out against a Dynamos attacking line that features the likes of Gustavo dos Santos, Florent Malouda, Adil Nabi, Robin Singh and Richard Gadze. The veteran defender will need all his experience to shut out a potent Delhi attacking force. Mendy’s passing accuracy of 85% also highlights his ability to pick out a pass from the back.Richard Gadze is Delhi’s highest scorer this season with four goals to his name so far. The Ghanaian’s blistering pace makes him an absolute nightmare for defenders to deal with. A truly two-footed player, he is also capable of making his presence felt from dead-ball situations.Raphael Augusto vs Florent MaloudaThe linchpin of Chennaiyin FC’s midfield, Raphael Augusto has been crucial to Chennai’s cause this season. Blessed with the ability to break down attacks, his total of 57 tackles is the most by any Chennaiyin FC player. Augusto has also made more interceptions (21) and blocks (17) than any other player from his side.Florent Malouda has been one of the most influential figures in Delhi Dynamos FC this season. The Frenchman has been involved in practically every Dynamos attack and has made six assists this season – the most by anyone in Hero ISL 2015. His hammer like left-foot also makes him a threat from distance and set-pieces.Stiven Mendoza vs John Arne RiiseTop scorer of this season, Stiven Mendoza created history in his last outing for Chennai by becoming the first player to score two hat-tricks in the Hero ISL. The Colombian has been in outstanding form this season and can be expected to have a big say in the outcome of the match on Tuesday. His current tally of nine goals is the most by any player in a single season.John Arne Riise has been one of the main reasons behind Delhi being the meanest defence in the league. The veteran defender will be crucial against a traditionally attacking Chennai side that will be high on confidence following a convincing win in their last outing against Kerala. Riise’s passing accuracy of 90% is the best by anyone in Delhi’s colours.Quotes:“They have been a very good team. They have conceded very few goals. I can tell that it [a win over Delhi Dynamos] won’t be easy”: Head coach Marco Materazzi“We know the Chennai situation this moment. The pressure is on Chennaiyin because we are playing at their home. So they will have to be the superior team.”: Head coach Roberto CarlosSquads:Chennaiyin FC: Karanjit Singh, Nidhin Lal, Apoula Edel Bete, Éder Monteiro Fernandes, Justin Stephen, Bernard Mendy, Abhishek Das, Lalhmangaihsanga Ralte, L.
