Real Madrid will need to play with intensity for 90 minutes and not just the first half if they are to have a chance of beating Barcelona in Sunday 's La Liga 'Clasico ' , according to Real coach Carlo Ancelotti . Ancelotti praised his side for their performance before the break in Sunday 's 2-0 win at home to Levante but said he was concerned by the way his players relaxed and let the visitors off the hook in the second period . A Gareth Bale double , his first goals in 10 matches , had put Real in control by halftime and they appeared to be cruising to a big win but Levante pushed Real hard in the second half and had chances to get back into the game . Gareth Bale scored his first goals in 10 games to help Real Madrid to a 2-0 win over Levante on Sunday . Bale has received a lot of criticism , but silenced his doubters with a La Liga double at the Bernabeu . It was not the dominant performance Real needed to silence their critics after three matches without a win but at least meant they will only be a point behind Barca when they run out at the Nou Camp . 'The whole team showed more desire and focus and they all understood what they had to do , ' Ancelotti told a news conference . 'We did that in one part of the match and on Sunday we need to do that for the whole match , ' added the Italian . Both goals were scored in the first half , and Carlo Ancelotti says they must have 90 minutes of intensity . Real Madrid travel to the Nou Camp to face Barcelona in their next match ; a potentially title-deciding game . 'We played with confidence in the first half , the second worries me a bit . 'We were more relaxed and played a more horizontal game . We lacked verticality . ' Bale , in particular , looked like he had a point to prove against Levante after he was one of the players targeted with whistles by Real fans upset with the team 's recent poor form . Ancelotti said Bale 's resurgence may have something to do with the return to action of midfielder Luka Modric , who he played with at Tottenham Hotspur , after a four-month injury layoff . Barcelona have been in brilliant form and are now top of La Liga after winning at the weekend . Real Madrid have slipped behind Barcelona to second in La Liga , and need to win to regain first position . 'Bale looked more motivated and more hungry , ' Ancelotti said . 'The presence of Modric offers more depth for Bale to link up with his team mates . 'They know each other well , they played together at Tottenham , and there 's no doubt that Bale is more comfortable with Modric on the pitch . ' Real have the rest of the week to prepare for Sunday 's showdown at Barca , who take a 2-1 lead into their Champions League last 16 , second leg at home to Manchester City on Wednesday .
