Benfica won the Portuguese league for the second year running on Sunday with one game to spare when they drew 0-0 at Vitoria Guimaraes and rivals Porto were held 1-1 at Belenenses. Porto were on course to take the title race to the final weekend when Colombia forward Jackson Martinez gave them a first-half lead, turning in a cross at the near post for his 21st goal of the season. But their chances evaporated on a hot afternoon when Tiago Caeiro snatched an 85th minute equaliser, firing home from close range after Dalcio’s pass opened up the Porto defence. The results meant that Benfica, who have won 26 of their 33 games and lost only three, stayed three points clear of Porto with one match each to play and cannot be caught because they have the better head-to-head record. Benfica won 2-0 at Porto in the first meeting and drew 0-0 in the return on their way to a record 34th league title, seven more than their old rivals. It was the first time for 31 years that the Eagles have won two titles in a row and a remarkable achievement for coach Jorge Jesus, who had to rebuild his side after several key members of last season’s treble-winning team were sold. “Benfica were better than our rivals and that’s why we reached the end in first place,” said the fiery 60-year-old who has also led his side to two Europa League finals in six years in charge. “With me, Benfica have always been challenging for or winning titles. We won this championship with the experience we gained over the last six seasons.”
