Barcelona placated their discontented fans and set up a mouth-watering Champions League semi-final against Manchester United with a nervy 1-0 win over Schalke 04 at the Nou Camp yesterday.

Barcelona's Yaya Toure (L) scores a goal against Schalke 04's goalkeeper Manuel Neuer (C) and Mercelo Bordon (R) during their Champions League quarter-final second leg soccer match at Camp Nou stadium in Barcelona, yesterday.

Barca, 1-0 up from the first leg of the quarter-final in Gelsenkirchen, were put under severe pressure in the opening half hour but the Schalke storm blew itself out just before halftime and the Catalans were gifted a goal after a series of mishaps in the German defence.

Midfielder Yaya Toure scuffed the ball in from close range in the 43rd minute after a Bojan Krkic cross from the right had ballooned off the foot of a defender and was then headed off the line.

Barca, the only non-English side in the last four, will host United at the Nou Camp in the first leg of the semi-final on April 23 and visit the Premier League leaders at Old Trafford the following week.

Liverpool face Chelsea for the third time in four seasons in the other semi-final.

"We are delighted to get to the semi-finals and especially to play against Manchester," club president Joan Laporta told Canal Plus television.

"We are really looking forward to it and I'm sure the fans will enjoy it too."

The match took place in an atmosphere of high tension following fans' protests over Barca's recent run of poor results and remarks by a high-ranking club official that Barcelona had used injuries to hide the fact that a number of players had been sidelined for indiscipline.

It looked as though Barca would be in for a difficult night when Schalke picked up where they had finished off in the first leg and put the home side under heavy pressure as they surged through the home side's ragged midfield.

LONG-RANGE EFFORT

Victor Valdes was almost caught out by a long-range effort from Halil Altintop but the Barca keeper managed to beat the striker's bobbling shot at the second attempt.

Although Barca struggled to get control of the game, they almost took the lead when Xavi was put in the clear after a neat through ball from Andres Iniesta but the midfielder was denied by a sharp one-handed save by Schalke keeper Manuel Neuer.

It was Schalke, though, who looked the more dangerous side in attack, midfielder Jermaine Jones sending a shot skidding just wide of the far post and striker Kevin Kuranyi missing a gilt-edged chance when he failed to get his foot to a cross a meter from the goal.

Schalke began to tire in the closing minutes of the half and Barca cashed in almost immediately thanks to a catalogue of mistakes in the German defence.

A low cross from Krkic almost ended up in the back of the net when it deflected off centre-back Marcelo Bordon, but Mladen Krstajic headed it clear as far as Toure who stabbed home from close range.

The goal steadied Barca and they almost extended their lead at the start of the second half, Iniesta only denied by a brilliant diving save from Neuer.

Barca will miss influential defender Carles Puyol for the first leg against United after he picked up a booking for a foul on Gerald Asamoah but they hope to have live-wire Argentine forward Lionel Messi back from injury.
