Madrid’s last roll of the dice in high-stakes Clasico

Real Madrid's season appeared disastrous a few weeks ago but if Carlo Ancelotti's side can finally beat rivals Barcelona in Sunday's La Liga Clasico, their title defence will be resuscitated.

Madrid were left licking their wounds after a Champions League quarter-final thrashing by Arsenal, and coach Ancelotti is poised to depart at the end of the season, but it could yet be with a major trophy in his hands.

Barcelona's European exit at the hands of Inter Milan on Tuesday brightened spirits in the Spanish capital and if Madrid can overhaul the Catalans at the top of the table, they could transform their season.

The nature of Madrid's rivalry with Barcelona means winning La Liga could either feel great or underwhelming, depending on how their nemesis fares in Europe.

With Barcelona's quadruple dream crushed by Inter, should Madrid defend their title they could even classify their season as a success.

The Catalans, who currently lead by four points with four matches remaining, would be left with only the Copa del Rey and Spanish Super Cup, both of which they won by beating Real Madrid in the final.

To do that Madrid must manage something they have not been able to pull off all season -- winning a Clasico.

"We will have a great opportunity, we have to prepare well -- it's an almost decisive match," said Ancelotti.

The teams have faced off three times and Barcelona triumphed on each occasion, in the two aforementioned finals and in the first league clash at the Santiago Bernabeu in October.

Barcelona netted 12 goals across the four games, conceding four, with Hansi Flick's side outplaying Madrid on each occasion.

However, their meeting in Seville in April in the Copa del Rey final was the closest Ancelotti's team have come.

Madrid took the game to extra-time and their Italian coach discovered a set-up which allowed his team to take Barca to the wire.

"The last match was competitive, we were very close to winning and I don't think we have to invent a lot of new things (tactically)," said Ancelotti.
