Barcelona president Joan Laporta is convinced Real Madrid are struggling with the pressure of staying in touch with the Liga leaders.
After victory over Tenerife last night, Barca are again four points clear of Real.
"Our team has done a good job and has put pressure on Madrid so that the Mallorca game is now a decisive match," said Laporta.
"We continue to set the pace. It is a historical league record and we are already on 93 points."
