ROME (AP):

A rare headed goal by Lionel Messi helped Barcelona beat Manchester United 2-0 in the Champions League final yesterday, giving the Spanish side its third European Cup title and third trophy in a magical season.

Samuel Eto'o put the Spanish champions ahead in the 10th minute and Messi's 70th-minute goal - his ninth in the Champions League this season - sealed the victory over the defending champions at the Stadio Olimpico.

The triumph completed a sweep of titles for 38-year-old Barcelona coach, Pep Guardiola, in his first season, after wins in the Spanish league and cup. The former Barcelona star, who started as a ball boy at Camp Nou, now joins the ranks of those who have won the title both as a player and a coach.

Guardiola became the youngest coach to win European soccer's top club competition since the European Cup became the Champions League in 1993.

Barcelona also won the trophy in 1992 and 2006.

"When I won as a player I was young and it was magnificent," Guardiola said of his 1992 triumph at Wembley against Sampdoria. "But now winning the treble at the first attempt is marvelous."

United had been chasing their fourth European Cup title, and fourth trophy this season after winning the Premier League, FIFA Club World Cup and League Cup.

But United were thoroughly outplayed by the Spanish side as Messi scored his 38th goal of an amazing year for Barcelona, which have 53 league and cup goals this season.

Diagonal ball

Xavi floated a diagonal ball into the United area to find Messi unmarked and the 5-fooot-7 (1.69 m) Argentina striker - renowned for his deft dribbling and shooting - used his head to loop the ball over United goalkeeper Edwin Van der Sar and into the net.

Messi set off colorful celebrations at one end of the stadium, filled with 62,467 fans and left English fans in silence.

The loss left Man United manager Alex Ferguson at 25 titles in 23 seasons. He failed to match Liverpool's Bob Paisley's three titles in the competition.

"We started the game brightly. We were confident and we could have been in front," Ferguson said. "We had the ball but didn't use it very well. ... We defended fantastically all season but they were two shoddy goals.

Good team

"We didn't play as well as we can, but they are a good team. We have to give them credit. Xavi (Hernandez) and (Andres) Iniesta can keep the ball all night. They made it very difficult."

South Korean winger Park Ji-sung became the first Asian to play in a Champions League final. He almost scored for United in the opening minute but his shot was deflected wide after Cristiano Ronaldo's free kick had been blocked by the goalkeeper. It was the nearest United came to scoring all night.

The victory also marked the first Champions League title for Thierry Henry, the French striker who was on the losing side when Arsenal went down to Barcelona in 2006.

"Finally, I've been waiting for so long to get this title and now finally today," said Henry, who had been doubtful for the final because of a knee injury. "The last five minutes were the longest of my life."
