Man Utd, Barcelona Complete Lineup

BELGRADE -- Manchester United completed a 3-0 aggregate win over AS Roma on Wednesday to join Liverpool and Chelsea in the Champions League semifinals in a repeat of last season for the three English teams.

They will be joined by 2006 winner Barcelona, which beat German side Schalke 04 by a single goal at home to secure a 2-0 aggregate victory, after Ivorian midfielder Yaya Toure scored shortly before halftime.

Liverpool now faces Chelsea for the third time in four seasons, while United, which last year went out to eventual winner AC Milan, plays Barcelona.

United manager Alex Ferguson was looking forward to his team's first competitive visit to Camp Nou since its 2-1 triumph over Bayern Munich in the 1999 final, thanks to two stoppagetime goals.

"Barcelona is a fantastic club and it is a marvelous stadium with great memories for us," Ferguson said.

"We can't go there and be negative, we have to go there and be positive and if we do that we have a good chance."

"You have opportunities in life when you have got something really special in your club, and I think we've got something special in this team."

A Carlos Tevez header off Owen Hargreaves' cross after 70 minutes gave United a 1-0 win at Old Trafford on Wednesday, as the English champion maintained its record of never losing a knockout tie in Europe after winning the away leg first.

They did so for the 14th time after weathering some nervy first-half moments, including a penalty which Roma midfielder Daniele de Rossi blazed over the bar on the half hour following Wes Brown's challenge on Mancini.

It was United third successive home win over Roma, following last year's 7-1 thrashing at the same stage of the competition and this season's 1-0 victory in the group stage.

With several key players rested ahead of Sunday's crunch Premier League clash with Arsenal, United looked uncomfortable for long spells before the Argentine calmed nerves with his fourth Champions League goal.

At Camp Nou, a simple finish from Yaya Toure booked Barcelona's berth in the last four after a furious start, in which Schalke had 10 shots in the opening 22 minutes.

Both goalkeepers made several good saves before Yaya Toure scored from close range after a goalline clearance fell kindly for him.

Barca, under pressure due to its poor domestic form, looked to be in for a difficult night as Schalke launched an early onslaught.

But the German side ran out of steam after conceding the goal and Barcelona held on comfortably in the second half to the relief of manager Frank Rijkaard.

Like Ferguson, Rijkaard was also relishing renewing old rivalries. United beat Barcelona 2-1 to win the now defunct Cup Winners Cup in 1991 and the teams twice drew 3-3 in the Champions League eight years later.

"I think we have got to get ready for two games against a team that is in top form and play very good football," Rijkaard said. "I am delighted to have the chance of playing against them."
