Barcelona remain top of the Primera Liga after a last-gasp Fernando Navarro own goal ended Real Mallorca's stubborn resistance and gifted the Catalans three points at the Nou Camp on Sunday.

The Spanish champions produced an unusually subdued performance, but eventually secured a win which keeps them top of the table after 30 rounds of La Liga.

With Ronaldinho missing following a bout of tonsilitis, coach Frank Rijkaard switched Lionel Messi to the left of his three-man attack.

The Argentinian was accompanied up front by the returning Samuel Eto'o and Ludovic Giuly.

The Frenchman had Barca's first shot of the match on eight minutes, but his weak effort failed to trouble Miguel Angel Moya.

The Mallorca goalkeeper was beaten four minutes later, however, when Deco crossed from the right and Mexican defender Rafael Marquez - playing in the holding role - crashed a powerful header against the post.

With the crowd willing them forward, Barcelona continued in search of an opening goal, but were frustrated as Mallorca got plenty of men behind the ball.

Eto'o came close to breaking the deadlock in the 26th minute with a stunning overhead kick, but the Cameroon international's effort went just over.

Despite their possession, the European champions were lacking inspiration and were lucky not to go behind four minutes later, when Victor Valdes brought down Argentinian forward Jonas Gutierrez.

The former Velez Sarsfield winger took the penalty himself, but saw his weak shot brilliantly saved by Valdes.

Deco then tried his luck from distance at the other end, and Giuly fired an angled drive wide of Moya's goal just before the break.

But it was a disappointing 45 minutes from Barcelona and the players were jeered off the pitch at the interval.

Things improved a little after the break as Messi tried to provide the spark of inspiration for the hosts.

Just after the restart, the young Argentina star shot straight at Moya from the edge of the area and popped up again with a cheeky back-heeled effort 10 minute into the second period.

Four minutes later, Italy full-back Gianluca Zambrotta blasted a long-range shot well over the bar as Barcelona began to look desperate.

Rijkaard sent on Xavi and Javier Saviola for Lilian Thuram and Giuly, and the duo almost had an immediate impact.

Xavi found Saviola with a lovely weighted pass after 66 minutes, but the South American, one-on-one with Moya, saw his shot well saved by the Mallorca goalkeeper from 12 yards out.

Six minutes later, Eto'o failed to get on the end of a Messi cross and Barcelona began to look as if they may have to settle for a draw.

But Rijkaard's side never gave up. After 85 minutes, substitute Juliano Belletti teed up Messi, but he could only shoot harmlessly wide.

With the seconds ticking away, Barcelona finally got the elusive goal when Navarro inadvertently turned the ball past Moya.

Saviola fired against the post following Xavi's free-kick, and the Mallorca defender could only divert the rebound into his own net to gift three valuable points to Barcelona.
