Real Mallorca coach Luis Aragones yesterday expressed his concern over the team's lack of persistence and concentration during matches.Mallorca ground out a creditable 2-2 draw at Rayo Vallecano on Sunday to stay fifth, but both Rayo goals came when Mallorca's defence was caught napping. We are doing enough to merit wins against some of these teams, said Aragones. But we are lacking conviction at the vital moment in each match. On Sunday Mallorca took the lead with a well controlled Ariel Ibagaza strike in the 4th minute after Finidi had neatly set the Argentine midfielder free. Mallorca subsequently relaxed and Rayo were soon to equalise when Quintana latched onto a free-kick which, instead of heading back across the goal mouth as Leo Franco was expecting, he headed straight into the gap left by the out-of-position Mallorca 'keeper. Rayo took the lead just before half-time when the unmarked Quevedo smashed an unstoppable shot into the Mallorca goal while Mallorca defenders were taking it easy on the edge of the area. It was an inspired Mallorca side that took to the field in the second half with Cameroon international Samuel Eto'o tying things up in the 62nd minute after a deadly shot from just inside the Rayo area.
