LISBON, May 11 (Reuters) - Sporting secured the second automatic Champions League spot when they beat Boavista 2-1 on the last day of Portuguese Premier League season on Sunday.
Porto, who clinched the championship more than a month ago, finished with 69 points from 30 matches after they were stripped of six points for alleged bribery of referees in the 2003-04 season.
Sporting finished second on 55 points and Vitoria Guimaraes third on 53.
Vitoria Guimaraes, who crushed Estrela Amadora 4-0 on Sunday, booked a place in the qualifying rounds of the Champions League for the first time.
Veteran Benfica playmaker Rui Costa did a lap of honour after his side's 3-0 victory over Vitoria Setubal on Sunday, his last match before retiring.
"Retired with my fans, retired with pride, I feel happy now," the 36-year-old told 50,000 supporters at the Luz stadium in Lisbon.
"There was a lot of emotion and sadness in my retirement but I feel proud of my career," he said.
Champions Porto, without nine first-team regulars, celebrated their third successive title with a 2-0 win at Naval on Saturday.
Benfica, Maritimo and Vitoria Setubal will play in the UEFA Cup.
