Bottom-of-the-table FC Goa play host to 2014 champions Atlético de Kolkata in Match 47 of Hero Indian Super League 2016 at the Jawaharlal Nehru Stadium in Fatorda on Thursday. The Gaurs go into this must-win tie having never beaten ATK before. They have also lost six out of their eleven matches so far this season and are in a bad space as regards their semis chances. Two out of their three overall victories, however, have come in their last four matches and that shows they are on the up in terms of performance. Be that as it may, even wins in their last three matches of the league stage don’t guarantee them a knockout appearance. One has to be honest that it will be nothing less than a miracle if they manage to reach their third successive semis. Meanwhile, ATK, besides Delhi Dynamos FC, have the least number of losses so far (2) but they have also drawn the most number of matches (6). In fact, all of their last three matches have ended in draws. They may be in the top half of the table but other teams are not far behind. However, if they win tomorrow they will definitely take a big step towards the semis.Head-to-Head: The inaugural season of the ISL saw the Gaurs succumb to a 2-1 defeat to ATK at home before playing out a 1-1 draw in Kolkata. The two teams again met in the semi-finals wherein a goalless draw was played out over both legs. In the deciding penalty shoot-out at Goa, Kolkata pipped the Gaurs 4-2. In Hero ISL 2015, the teams played out a 1-1 draw at Goa before Kolkata humbled them 4-0 at home. Earlier this season, the teams again played out a 1-1 draw at Kolkata.Form Guide (last five matches):FC Goa: L-W-L-W-DAtlético de Kolkata: W-L-D-D-DRafael Coelho vs Arnab MondalFC Goa’s top-scorer with three goals, Rafael Coelho will hold the key in attack tomorrow. The 28-year-old has been instrumental going forward, having the most shots on target for his team (9). Much of Goa’s attacks centres around him and he will need to see a lot of the ball if Goa are to have any chance of winning this match.Arnab Mondal has been a pillar at the back for ATK this season. He wins most aerial duels and his precise tackling and clever interceptions make him a difficult customer to come up against. His team though has conceded goals at crucial moments and he needs to make sure that doesn’t happen again at this important juncture of the league stage.Richarlyson vs Borja FernandezRicharlyson has been an important figure in the centre of the field for his team. With one goal and two assists, the Brazilian has shown he is quite capable of pulling the strings from midfield when it comes to offense, and he really needs a good day at the office to deal with the threat that ATK possess in midfield.Kolkata’s captain Borja Fernandez has been a reliable figure in midfield from day one of the league. This season again, he has been involved in the most number of tackles for his team (32). He is capable of creating opportunities while going forward, at the same time he is equally efficient in breaking down opponents’ attacks. He will definitely be a key figure tomorrow.Rafael Dumas vs Helder PostigaRafael Dumas is one of the few Goa players to have caught the eye this season. He is a strong defender and makes life difficult for opposition attackers. His tackling and intercepting abilities have plenty of credibility. In a match Goa cannot afford to lose, he has to see to it that his team does not concede. Besides Luciano Sobrosa, he is coming back from a two-game suspension and that should serve as extra motivation for him.Marquee player Helder Postiga has influenced a lot of Kolkata attacks in the matches he has played this season. With two goals and two assists, he is a dangerous player to deal with both inside and outside the box. With deft touches and good aerial qualities, Postiga will be the player Kolkata will look to score in this important fixture.Squads:FC Goa: Laxmikanth Kattimani, Subhasish Roy Chowdhury, Sukhdev Patil, Lucio, Debabrata Roy, Denzil Franco, Fulganco Cardozo, Gregory Arnolin, Keenan Almeida, Raju Gaikwad, Sanjay Balmuchu, Joffre, Mandar Rao Dessai, Pratesh Shirodkar, Richarlyson, Romeo Fernandes, Trindade Goncalves, Julio Cesar, Rafael Coelho, Reinaldo, Robin Singh, Luciano Sobrosa, Rafael DumasAtlético de Kolkata: Debjit Majumder, Dani Mallo, Shilton Paul, Arnab Mondal, Henrique Fonseca Sereno, Jose Arroyo, Keegan Pereira, Kinshuk Debnath, Prabir Das, Pritam Kotal, Robert Lalthamuana, Abinash Ruidas, Bidyananda Singh, Bikash Jairu, Bikramjit Singh, Borja Fernandez, Javi Lara, Jewel Raja, Lalrindika Ralte, Ofentse Nato, Sameehg Doutie, Stephen Pearson, Helder Postiga, Ian Hume, Juan Belencoso
