(source) Barcelona's title celebrations fell flat as they surrendered a one-goal advantage to slip to a 2-1 defeat at Real Mallorca.
With Real Madrid's defeat against Villarreal on Saturday night handing the Catalan side the Primera Division crown, expectations were of a showcase of Barca's attacking skills.
Samuel Eto'o scored after 10 minutes to set the expected tone but from there on it was a disappointing day for both player and club, as the striker missed a hatful of chances - including a last-gasp penalty.
At the other end a fine strike from the impressive Juan Arango and a deft Loureiro Santana header sealed the points for the hosts.
Mallorca full-back Josemi had the first chance of the game but despite doing well to win an eighth-minute header 12 yards out, his attempt on goal was tame.
Eto'o made no such mistake two minutes later when he buried Bojan Krcic's cross from similar range.
From that point, home goalkeeper Miguel Moya took centre stage, repeatedly frustrating the champions - and in particular Eto'o.
His first save came moments after the opening goal when he held a speculative Alexander Hleb effort, but there was better to come.
After 20 minutes he denied Eto'o from the centre of the box and eight minutes later he made an even better stop, charging from his line to meet the Cameroon forward and standing firm to repel a powerful strike.
The ball rebounded to Eto'o but as he attempted to slot home from a tight angle, Josemi made a fine sliding block.
Eric Abidal nearly put Barca goalkeeper Oier Olazabal in trouble with a wayward back pass, but the latter was able to boot to safety.
As the first half came to end, Eto'o had one more chance, fashioned by the hardworking Eidur Gudjohnsen and Bojan, but again could not beat Moya.
Arango started the second period in lively mood for Mallorca, orchestrating a neat passing move on the left flank that was broken up by the backtracking Gudjohnsen.
There were two more chances for Eto'o to put Barca clear, one smothered by Moya and the second blasted high into the stands.
Then, with 18 minutes left, an Abidal foul allowed Arango to line-up from 20 yards and the Venezuelan lashed it home in some style.
He had a second dead-ball chance only seconds later when Xavi was penalised but this time he was off target.
By now, though, the visitors were looking tired and appeared to be inviting a second.
It came in the 79th minute when Jose Manuel Jurado's cross was dealt with hesitantly by the back four, who allowed Santana to steal in and deflect the ball across goal and over the line.
Arango looked to capitalise on Barca's flagging energy levels, testing Olazabal with a swerving shot from 30 yards.
Eto'o was to suffer more disappointment before the end, first heading against the crossbar with only seconds left and then clattering the post from the penalty spot after he had been fouled by Jose Luis Marti.
please, no hotlinking.
