( CNN ) -- An error from Brazilian goalkeeper Heurelho Gomes saw Real Madrid win 1-0 at Tottenham on Wednesday to reach the semifinals of the Champions League 5-0 on aggregate . Gomes allowed a second-half shot from Cristiano Ronaldo to slip through his fingers and crawl over the goalline to ensure the Spanish side secured a mouth- watering last four showdown with bitter rivals Barcelona . Jose Mourinho 's side held a comfortable lead from the first leg at the Bernabeu but , despite that advantage , the Real Madrid coach still decided to play his strongest side at White Hart Lane . Messi sets record as Barca reach semifinals . And the visitors had to hold on in the first 45 minutes as Tottenham had two good penalty appeals turned down , while Gareth Bale had the ball in the Madrid net , but his goal was ruled out for offside . However , just five minutes into the second half , the tie ended when Ronaldo attempted a strike from 25 yards out that Gomes should have dealt with comfortably , only for the keeper to fumble the shot into the net . Ramon Pavlyuchenko nearly levelled for Spurs from Rafael Van der Vaart 's cross and defender William Gallas hit the post from close range , but Real were never in danger of losing their advantage . The result means that Barcelona and Real Madrid will now clash four times in just 18 days in what will be a monumental series of 'El Clasico ' encounters . First the teams meet this weekend at the Bernabeu in La Liga , before they face each other four days later in the Spanish Cup final in Valencia prior to their two Champions League showdowns . Mourinho -- who is the first coach to ever lead four different teams to the Champions League semifinals -- told ITV Sport : `` Anything can happen in a semifinal , but we have two other matches to come against Barcelona before then and must concentrate on those games first .
