( CNN ) -- Real Madrid coach Jose Mourinho insisted his team can still win Spain 's La Liga despite their humiliating 5-0 defeat to arch-rivals Barcelona in the Camp Nou on Monday night . Mourinho admitted Real had suffered a `` much deserved loss '' in the first Clasico clash of the season , but claimed it was not a true reflection of the abilities of the two sides . `` It was n't an embarrassment , '' the 47-year-old told a post-match press conference . `` It 's the biggest loss of my career but it 's an easy loss to swallow because it 's a loss in a game that you have no chance of winning . '' `` [ There was ] a team that played to its maximum potential and a team that played very poorly . It 's a much deserved loss , but again , it was an easy loss to swallow . '' Five-star Barcelona thrash Real Madrid . It was Mourinho 's first defeat since arriving at the Bernabeu and left reigning champions Barcelona two points clear of Los Blancos at the of the top of the standings . But with 25 matches still remaining in Spanish season , the Portuguese is still optimistic his team can hit back . `` The league championship will be decided a long time from now , '' he said . `` After the match , I told the players that the league is n't over yet . We have to have mental fortitude . `` When you win important things , you have a reason to cry for joy and when someone scores five against you , you have to leave with an eagerness to play the next game . `` Barcelona is a finished product . Real Madrid , even though it has been playing well , is n't a finished product . But the result today was not indicative of the difference that exists between both teams . '' The match had been billed as a clash between two of the world 's best and most evenly-matched teams , but Pep Guardiola 's men dominated in front of their home fans . They were 2-0 up inside 20 minutes through goals from Xavi and Pedro . A brace from David Villa and a late strike by substitute Jeffren completed the humiliation and Barca coach Guardiola could not have been more satisfied . `` How we did it , that makes us proud , '' he told the club 's official website . `` Now just let us sit back and enjoy that win . '' He singled out Argentina ace Lionel Messi , who emerged on top in his personal duel with Real 's fellow superstar Cristiano Ronaldo . `` Messi is the best of them all . In all aspects of his game he is just the best . '' Mourinho will hope his team can bounce back in a difficult home fixture against fifth-placed Valencia on Saturday , while Barcelona travel to Osasuna on the same day .
