Mallorca attacker Giovani dos Santos has warned the Real Madrid squad that they will be up against it when the two clubs meet on Sunday.
The forward, who came through the ranks at Barcelona's youth system, La Masia, believes the pressures of the title race could work against the Spanish champions, and is determined to spring a shock result.
"The visit of Madrid, one of the biggest clubs in the world, is a huge motivation for us to up our game," he stated at a pre-match press conference.
"We really need a result after three defeats [against Getafe, Granada and Sevilla] and Madrid haven't been playing great recently. If you want to beat Madrid, you have to attack them.
"They have the added pressure of knowing that Barcelona are running away with the league and therefore they'll go out and attack us from the off, and we'll try to take advantage of the space they will leave."
