Table-toppers Mumbai City FC play host to Chennaiyin FC in Match 46 of Hero Indian Super League 2016 at the Mumbai Football Arena on Wednesday. The Mumbaikars will look to put one foot in the semis with a win in front of rapturous home support. However, it won’t be easy as the Super Machans have never lost to Mumbai, having scored 14 and conceded just two goals in the process. Mumbai have won the most number of matches this season so far (5), and they will be high on confidence coming on the back of a comprehensive 5-0 victory over Kerala Blasters FC in their last match. Chennaiyin FC, who have just one win in their last seven matches, rallied to a draw in their last outing against Atlético de Kolkata, needing a 77th-minute equaliser from Davide Succi to secure a point. Their form has been indifferent so far, winning three and losing three out of their 11 matches. A win against one of the favourites this season would do them a world of good in their quest for a semis spot.Head-to-head: The inaugural season saw Chennaiyin put eight past Mumbai over the course of two matches, with the Super Machans winning 5-1 at home and 3-0 away. Hero ISL 2015 saw Chennaiyin again do the double over Mumbai with them winning 3-0 at home and 2-0 away. Earlier this season, the teams played out a 1-1 draw in Chennai.Form guide (last five matches):Mumbai City FC: D-W-L-D-WChennaiyin FC: D-L-L-W-DDiego Forlan vs Bernard MendyMumbai City’s marquee player Diego Forlan has been in sparkling form. He has this season’s only hat-trick under his belt, which he achieved in their last match against Kerala Blasters FC. He is expected to go from strength to strength now that he has tasted blood. Deadly inside the box as well as a constant threat during set-pieces, Forlan is one player who can throw a spanner in the works for Chennaiyin on Wednesday.Chennaiyin FC’s centre-back Bernard Mendy has been Mister Reliable since the inaugural season of the league. However on Wednesday, he will have a tough task of dealing with the likes of Sunil Chhetri and Diego Forlan. The French international, with nine appearances so far this season, has been solid at the back for the Super Machans. Good when it comes to aerial duels, he rarely allows opposition attackers to outpace him. He is also a dangerous target from set-pieces.Matias Defederico vs Raphael AugustoMatias Defederico has undoubtedly been Mumbai’s in-form midfielder. Having bagged two goals and three assists in 10 appearances, the Argentine is a constant threat going forward. The fast, left-footed player always causes problems for opposition defenders and his contribution from midfield will be a deciding factor as to how Mumbai perform tomorrow.Chennaiyin FC’s Raphael Augusto is another midfielder who is capable of pulling the strings from midfield. He has been instrumental in quite a few games, having played the second most number of minutes (880), only behind Mehrajuddin Wadoo (990), for his team. Most importantly, he has four assists to his name. Against an in-form Mumbai midfield, he will need to see a lot of the ball if the Super Machans are to stop the hosts in their tracks.Lucian Goian vs Davide SucciLucian Goian has been a pillar at the back for Mumbai City FC. The 33-year-old Romanian brings plenty of experience to the squad and has the ability to win aerial duels besides making important tackles and interceptions. Mumbai have the best defence so far in the league, and for that they have Goian to thank. His performance will be crucial tomorrow against a strong Chennaiyin forward line.Davide Succi has been in good scoring touch for Chennaiyin of late, with the Italian forward scoring twice in his last two outings, including a late equaliser in their last match against Kolkata. Having a total of three goals and an assist, Succi is a key player for his team, and a constant threat in the opposition box. The tall forward is also an aerial threat and Mumbai will have to be wary of him.Squads:Mumbai City FC: Roberto Volpato Neto, Amrinder Singh, Albino Gomes, Gerson Vieira, Lucian Goian, Facundo Cardozo, Anwar Ali, Aiborlang Khongjee, Lalhmangaihsanga Ralte, Lalchhuanmawia Fanai, Ashutosh Mehta, Krisztian Vadocz, Leo Costa, Jackichand Singh, Saran Singh, Sehnaj Singh, Boithang Haokip, David Lalrinmuana, Matias Defederico, Otacilio Brito Alves, Sony Norde, Diego Forlan, Thiago Cunha, Sunil Chhetri, Udanta SinghChennaiyin FC: Karanjit Singh, Pawan Kumar, Duwayne Kerr, Bernard Mendy, Mehrajuddin Wadoo, Eli Sabia, Eder Monterio, Jerry Lalrinzuala, Abhishek Das, John Arne Riise, Baljit Sahni, Hans Mulder, Manuele Blasi, Thoi Singh, Raphael Augusto, Harmanjot Singh Khabra, Davide Succi, Maurizio Peluso, Bedashwor Singh, Uttam Rai, Jeje Lalpekhlua, Zakeer Mundampara, Jayesh Rane, Daniel Lalhlimpuia
