FC Goa will look to keep their semi-finals hopes alive when they play host to NorthEast United FC at the Jawaharlal Nehru Stadium in Fatorda on Friday. The hosts have had a torrid season so far and will desperately be looking for a win as their last match ended in a 2-1 defeat to Kerala Blasters FC. However, the Gaurs won’t have the services of Gregory Arnolin and Richarlyson, who have been ruled out through suspensions. Going into the match without their top goal-scorer Emiliano Alfaro on account of a suspension, NorthEast United FC are also desperate to bring their campaign back on track, having of late run into a bad patch with three consecutive losses at home with the last one coming against Mumbai City FC. Thus, a tightly contested matchup of Hero Indian Super League 2016 is in the offing on Friday evening, with both teams seeking maximum points.Head-to-head: FC Goa drew 1-1 away before winning 3-0 at home in Hero ISL 2014. In Hero ISL 2015, they won 3-1 away before ending up tied 1-1 at home. This year, NorthEast United FC notched up a 2-0 win though, thanks to a brace from Alfaro.Form Guide (last five matches):FC Goa: W-L-L-W-LNorthEast United FC: W-D-L-L-LRafael Dumas vs Robert CullenRafael Dumas has been one of the regulars for FC Goa this season. The 21-year-old has shown maturity beyond his years to prove his worth in the back. The Brazilian is brilliant at making neat tackles and interceptions but it is his clean passing that is likely to stand the Gaurs in good stead on Friday against a team facing some serious defence concerns.In his four appearances for the Highlanders, Robert Cullen has shown a lot of promise. The Japanese striker has European experience and can run through any defence on his day. His potency in front of goal will be a threat to the Goa backline. Zico will have to find a way to deal with him.Mandar Rao Dessai vs Katsumi YusaMandar Rao Dessai has amassed a lot of game time and has slowly established himself in the Gaurs line-up. His ability to keep control of the ball is crucial during pressure situations. The 24-year-old’s passing qualities will be vital to Goa’s chances on Friday.Katsumi Yusa has looked bright for the Highlanders in Hero ISL 2016. Having played every minute, the Japanese playmaker has contributed both in attack as well as defence. His knack of earning set-pieces, along with blistering pace and quick passing, makes him a dangerous player.Rafael Coelho vs Mailson AlvesRafael Coelho has been one of the few bright spots for coach Zico’s side. He has got the much-needed goals for them and has been a threat every time with the ball at his feet. He is one of the few strikers this season who is equally effective in the air. He is definitely a nightmare for opposition defence.Mailson Alves has returned from injury and has become a mainstay in defence for the Highlanders. With his exceptional passing, the Brazilian is a valuable asset and goes about his job in a no-nonsense manner. The 28-year-old can also be a threat in the air. The Gaurs will have a hard time dealing with him.Squads:FC Goa: Laxmikanth Kattimani, Subhasish Roy Chowdhury, Sukhdev Patil, Lucio, Debabrata Roy, Denzil Franco, Fulganco Cardozo, Gregory Arnolin, Keenan Almeida, Luciano Sobrosa, Rafael Dumas, Raju Gaikwad, Sanjay Balmuchu, Joffre, Mandar Rao Dessai, Pratesh Shirodkar, Richarlyson, Romeo Fernandes, Sahil Tavora, Trindade Goncalves, Julio Cesar, Rafael Coelho, Reinaldo, Robin SinghNorthEast United FC: Subrata Paul, TP Rehenesh, Wellington Gomes, Salam Ranjan Singh, Nirmal Chettri, Shouvik Ghosh, Robin Gurung, Reagan Singh, Mailson Alves, Gustavo Lazzaretti, Didier Zokora, Fanai Lalrempuia, Holicharan Narzary, Jerry Mawihmingthanga, Katsumi Yusa, Koffi Christian N'dri, Lallianzuala Chhangte, Rowllin Borges, Seityasen Singh, Wellington Priori, Romaric, Emiliano Alfaro, Nicolas Velez, Sasha Aneff, Robert Cullen, Sumeet Passi
