Top four a class above: Farah Wests Tigers captain Robbie Farah believes this season's premiers will come from the teams currently in the top four and warned Manly will be tough to beat after moving into third place with their win at Campbelltown Stadium. The Sea Eagles 36-18 defeat of the Tigers on Monday night has opened a three point buffer between the top four and the next three teams - Canterbury, Cronulla and Canberra - and Farah predicted none of those teams would rise to become the grand final winner. "I can only really think there is four teams who can win it and that is the top four," Farah said. I think the Roosters and Souths, they have just got so many quality players - both sides. "I can only really think there is four teams who can win it": Robbie Farah. Asked about Manly, who have leapfrogged the Storm on for-and-against, Farah said: "They will be up there, they have got the experience come September so you can't write them off." The Sea Eagles are expected to secure their ninth consecutive finals appearance with one more win and would be strong favourites to do so against Parramatta next weekend. However, Manly coach Geoff Toovey was not impressed by his side's performance and the Tigers camp believe the Sea Eagles were there to be beaten if they had taken their chances. "We did enough to win, it wasn't great football but I thought the boys gutsed it out there," Toovey said. In the first half they had six or sevens sets in a row so it was really solid defence on our line that I think won us the match. Five-eighth Kieran Foran was outstanding in the win and set up three of his side's six tries but Toovey was reluctant to praise any individual, saying: "I thought he played fairly well but I didn't think there was any great stand out." For Wests, the focus is now on finishing the season in the best possible fashion after being stalled six points outside the top eight with six rounds before the finals. "We didn't execute our plays and we went away from what we wanted to do," Tigers coach Mick Potter said. We fell into the trap of trying to go around Manly and we shouldn't have. Potter said he believed his team was still in the match at 16-6 down at halftime but Farah admitted they had blown any hope after the restart. "We started the second half with two play-the-ball errors, a penalty and then they scored off another error," Farah said. Winning is a habit so losing probably is too. It has been the story of our season...we've learnt how to lose. We need to build some sort of platform going into next year and build some positives for a pre-season where there are going to be personel changes and young kids coming into the first grade squad. Obviously we can't make the semis but we need to take something out of this last six weeks.
