SEVILLE — Lionel Messi and Luis Suarez scored twice as Barcelona won 5-0 at Real Betis Sunday with five second-half goals to increase its Spanish league lead. Ivan Rakitic also scored for the Catalan club, which moved 11 points ahead of Atletico Madrid at the start of La Liga’s second half. After 20 rounds, Barcelona has a 14-point lead over third-placed Valencia, and is 19 points in front of rival Real Madrid, which has a game in hand. “There are 18 games left, that’s a lot,” Barcelona coach Ernesto Valverde said. “But with each win we will be taking a big step toward the title.” After an even first half at Benito Villamarin Stadium, Barcelona gained control of the match when Rakitic opened the scoring after a breakaway early in the second half. Messi scored his first goal five minutes later and Suarez quickly added to the lead. Messi’s second goal in the 80th was one to admire, with the Argentine entering the area and going past two defenders before calmly finding the net. Suarez closed the scoring just before the end, reaching his 100th goal in 114 matches with Barcelona. Messi, who has scored seven goals in his last six games, leads the league with 19 goals, four more than Suarez. The Uruguay striker has scored at least a goal in seven consecutive league games. He has 10 goals in his last eight matches in all competitions. Barcelona was coming off a 1-0 defeat at city rival Espanyol in the quarterfinals of the Copa del Rey, a result that ended the team’s 29-match unbeaten streak. It remains without a loss in the league. Betis, which dropped to 11th place, was coming off two straight wins, one of them at city rival Sevilla. Barcelona defender Thomas Vermaelen came off with an apparent muscle injury before halftime. He was replaced by France international Samuel Umtiti, who returned after a long injury layoff. On Saturday, Atletico was held to a 1-1 home draw against Girona, while Valencia lost 2-1 at Las Palmas. Real Madrid routed Deportivo La Coruna 7-1 at Santiago Bernabeu Stadium Sunday, with Cristiano Ronaldo and Gareth Bale scoring two goals each. Inter Milan sinks low Inter Milan fell further behind in the Serie A title race Sunday after a scrappy 1-1 home draw with Champions League-chasing Roma left it 11 points behind leader Napoli. Matias Vecino equalized with a late header for Inter after Stephan El Shaarawy had capitalized on awful defending to clip home goalkeeper Alisson’s huge clearance in the 32nd minute to open the scoring. Uruguayan Vecino met a whipped Marcelo Brozovic cross to beat an outstanding Alisson, who had made two superb second-half saves from Mauro Icardi, and keep Luciano Spalletti’s side in the top four, level on 43 points with third-placed Lazio and three ahead of Roma. However it is winless in six games in the league and no longer look like title contenders, while Roma, which stays fifth on 40 points, has fallen even further behind after picking up just ten points from a possible 24 since beating Lazio in mid-November. Eusebio Di Francesco’s side is now 12 points behind Napoli, which extended its lead at the top to four points when Dries Mertens ended a long goal drought to give his team a 1-0 victory at Atalanta. Belgian international Mertens’s 65th-minute strike ended a league dry spell that stretched back to October 29, getting behind the defense and flashing his 11th goal of the season past Atalanta goalkeeper Etrit Berisha. — Agencies
