MADRID — Four-time World Player of the Year Lionel Messi has urged his Barcelona teammates not to miss out on the second chance they have been gifted to retain their La Liga title. Barca seemed all but out of the title race after conceding a last-minute equalizer to draw 2-2 at home to relegation-threatened Getafe last weekend. However, leader Atletico Madrid subsequently lost 2-0 away at Levante, whilst Real Madrid has drawn twice against Valencia and Valladolid in the past week to leave it in third place, four points adrift of Atletico with just two games to play. Barcelona remains three points adrift of Diego Simeone's men itself, but will win the league if it wins its two remaining games away to Elche Sunday and then when Atletico visits the Camp Nou on the final weekend of the season. “We are in a better position today than we were a few weeks ago,” said Messi. “We can see that we have an opportunity to win the league. We need to take advantage of this moment and not let it escape.” Gerardo Martino's men are sure to face a tough task this weekend, though, as Elche is in need of points itself as it sits just three points above the relegation zone and has yet to be beaten at home in nine league games so far in 2014. Barca will again be without the injured Gerard Pique, Jordi Alba and Neymar, although all three are hopeful of being fit for the potential title decider against Atletico next weekend. However, should Barca fail to win this weekend, Atletico can mathematically seal its first title in 18 years with victory over Malaga at the Vicente Calderon. Atletico has injury worries itself as top scorer Diego Costa looks set to miss out due to a hamstring injury, which could yet endanger his participation in the clash with Barcelona and in the Champions League final against Real Madrid on May 24. Diego Godin is also suspended for Los Rojiblancos, but right-back Juanfran returns from suspension having missed the defeat at Levante. However, forward Adrian Lopez still believes home advantage should be enough to edge his side closer to the title. “We know that we are very strong at home in front of our own fans,” he said Friday. “It is a key game. With all that we are playing for to get three points Sunday would be a huge step forward. “We know the atmosphere will be incredible. The fans are going to be very excited having watched what has been a great season for us and it could end in a great and happy way for everyone.” David Villa is likely to replace Costa with Raul Garcia moving forward from the midfield role he has deployed in recent weeks to make space for the return of Arda Turan. Real Madrid needs to win away to Celta Vigo to maintain any hope of catching Atletico, but is likely to be without a host of first-team regulars, including Cristiano Ronaldo. The current World Player of the Year limped off with a minor muscular problem less than 10 minutes into Real's 1-1 draw with Valladolid Wednesday and is unlikely to be risked with the Champions League final against Atletico just two weeks away. Pepe and Angel di Maria also picked up injuries against Valladolid, but Gareth Bale should return after missing the trip to the Jose Zorilla with a knock. At the bottom, Osasuna could join Real Betis in being mathematically relegated should it lose away to Espanyol and any two of Getafe, Valladolid and Almeria win when they face Sevilla, Betis and Granada respectively. — Agencies
