Sevilla manager Unai Emery has admitted that his side are "lacking a bit of everything" this season.
The Red and Whites are currently 12th in La Liga, having finished fifth last season while also winning the Europa League.
Emery's team face leaders Real Madrid tomorrow evening, and the 44-year-old is hoping that his side can up their game against Los Blancos.
"The game is very important above all because of the necessity we have to improve our credibility, which is below the level we want at the moment," he told reporters.
"We haven't found the best version of Sevilla over 90 minutes (this season). Honestly, we're lacking a bit of everything. The team is growing but there are things we need to get right. Tomorrow we can take another step in the right direction and get our intensity levels up a bit more."
Sevilla have had just one clean sheet in their previous seven league games, while Real forward Cristiano Ronaldo has found the net in his last four appearances against Emery's side.
