European champions Real Madrid will expect to take another step closer to becoming the first team in 25 years to retain the Champions League when they host Schalke on Tuesday holding a 2-0 lead from the first leg of their last 16 tie.
Madrid have strung together 10 consecutive victories in Europe stretching back to their successful run to their 10th European Cup last season, but have found the going a lot tougher domestically in 2015.
Los Blancos surrendered their lead at the top of La Liga at the weekend as they were beaten 1-0 at Athletic Bilbao, whilst Barcelona thrashed Rayo Vallecano 6-1.
That was Madrid's fourth defeat in 14 games this year with coach Carlo Ancelotti admitting he was at a loss to explain how his star-studded strike force of Cristiano Ronaldo, Karim Benzema and Gareth Bale has so suddenly gone off the boil.
"It seems strange to say Madrid have a problem up front when we have scored so many goals throughout the season, but I think it is the truth," said the Italian on Saturday.
However, captain Iker Casillas has insisted that they won't suffer a hangover from their La Liga woes at the Bernabeu.
"This competition is different. For Madrid fans it means everything," he told the club's website.
Schalke were on the receiving end on Real's run towards the title at the same stage of the competition last season in a 9-2 aggregate hammering.
