MANCHESTER United completed a 3-0 aggregate win over AS Roma on Wednesday to join Liverpool and Chelsea in the Champions league semifinals as the three English teams repeated last season's success.

They will be joined by 2006 winners 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 will face Chelsea in the Champions League semifinals for the third time in four seasons after beating the side in 2005 and last year while United, which lost last term to eventual winner AC Milan, will face Barcelona.

Barcelona hosts Manchester United on April 23. The return leg six is set for April 29.

United manager Alex Ferguson was looking forward to his team's first competitive visit to the Nou Camp since their 1999 Champions League triumph there when the side beat Bayern Munich 2-1 thanks to two stoppage time goals.

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

"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."

Carlos Tevez scored with a diving header off a cross from Owen Hargreaves, long after Daniele de Rossi missed a penalty for the Italian team in the 30th.

"We put in a good game and a good performance,'' Roma coach Luciano Spalletti said. "We had to take one or two risks. It was important to exploit chances when we actually created them, but didn't capitalize on them. If we had it would have changed the face of the game.''

Barcelona took the lead when Bojan Krkic's cross was deflected up and headed around before falling to Touré in the box.

Ronaldinho and Deco, two players who have missed lengthy periods to injury, were not in the lineup.

"This team deserves a lot of credit for what it's done. It's fought to the end to achieve this result,'' Barcelona president Joan Laporta said. "It's a moment to savor.''

Schalke coach Mirko Slomka said his team didn't play to its potential.

"We played 90 very good minutes out of the 180 against Barcelona and the two times we let our guard down they took advantage,'' Slomka said.

Liverpool hosts Chelsea on April 22 and visits Stamford Bridge on April 30.

The Champions League final is scheduled to be played in Moscow on May 21.
