LONDON - Real Madrid set up a titanic Champions League semi-final with arch-rivals Barcelona by beating Tottenham Hotspur 1-0 at White Hart Lane on Wednesday to complete a 5-0 aggregate victory.

Cristiano Ronaldo scored one of the softest goals of his career when Spurs keeper Heurelho Gomes allowed a long-range shot bounce out of his hands in the 50th minute and failed to retrieve the ball as it bounced agonisingly over the line.

Real, 4-0 up from last week's first leg, were never in danger of suffering what would have been the biggest reversal since European club competition began in 1955 but needed to concentrate fully to keep a lively Spurs team at bay.

The closest Champions League debutants Spurs came to scoring was when Gareth Bale had a first-half goal ruled out because Luka Modric was offside.

"It will be a very intense semi-final," Real midfielder Xabi Alonso told Spanish television.

"We know each other very well, everyone has been talking about it and now it is a fact. Bring it on."

Spurs set about their virtually impossible task with Bale and Aaron Lennon outpacing Alvaro Arbeloa and Sergio Ramos at will on the flanks before whipping in balls that put Real under pressure.

One run by Bale, when he blazed past Ramos, brought an astonished look to the face of Real coach Jose Mourinho, but it was Lennon who created a good chance after 27 minutes.

Penalty Appeals

Lennon left Arbeloa in his wake again only for Roman Pavlyuchenko to blast the ball into the upper tier of the stands.

Spurs also had three penalty appeals turned down as they continued to go forward, Italian referee Nicola Rizzoli waving away claims after Bale, Modric and Pavlyuchenko all went down under challenges.

Real, naturally enough, were content to sit back and only gave the home defence one moment of real concern in the first half when Ramos forced Gomes to make a fine save from a header and Emmanuel Adebayor lashed the follow-up wide.

The second half lacked the intensity of the first after Ronaldo's goal as Real cruised into the last four, maintaining their challenge for a 10th European Cup title ahead of the final at Wembley Stadium on May 28.

"We knew before the game it was going to be a difficult challenge," said Spurs winger Bale. "It's disappointing but we have had a great run in the Champions League.

"We lost to a better team. They were the better club over the two legs. I don't think anyone expected us to get this far."
