Xavi, Samuel Eto'o and Henry opened the scoring in the first half before substitute Giovanni Dos Santos rounded off the victory with a late fourth against a Happy Valley-Kitchee select team.

The win in front of a half-full Hong Kong Stadium, where just over 23,000 fans braved terrible weather conditions, helped Barcelona to complete a successful Asian tour.

Barcelona coach Frank Rijkaard was delighted with his team's performance.

"Of course the difference in strength between the two teams was obvious. But, if you don't keep up a good level of organisation you can give the opponent wings and hope. For that reason I was happy with the game," he said.

The Spanish giants dominated from the start, and a side that also included star striker Ronaldinho needed just twenty-one minutes to break the deadlock, with Spanish international midfielder Xavi finishing off a three-man move.

Andres Iniesta slid through a pass after Eto'o had held up the ball outside the area, with Xavi poking home past goalkeeper Fan Chun Yip.

Barcelona scored their second goal six minutes later.

Thierry Henry, playing in his preferred role as a central striker, passed to Ronaldinho. The Brazilian pulled the ball back to Eto'o from the left, and the 26-year-old made no mistake from the edge of the penalty area.

Henry netted a spectacular third ten minutes before the interval, diverting a first-time Eto'o cross into the top corner with a diving header.

"I am happy that, thanks to the work that he is doing, he is growing in strength physically. He won't loose his head and the goal was just a normal thing for him," Rijkaard said of Henry.

The three strikers left the game in the 61st minute and substitute Dos Santos completed the rout with a well-taken strike with just eight minutes remaining.

The 18-year-old Mexican sensation took a superb through-ball from Xavi in his stride and dispatched with ease for his fourth pre-season goal.

Barcelona showed little signs of tiredness despite the wet, energy-sapping conditions.

Heavy rain made for a slippy pitch although the Hong Kong fans would have been grateful that the match even took place. The city was hit by typhoon Pabuk on Friday causing the game to be moved back by a day.

Barcelona now head back to Spain on the back of a successful tour. This victory followed wins against Beijing Guoan and Yokohama Marinos.

The team did not concede a single goal during the tour and the successful integration of new signings Thierry Henry and Yaya Toure will give them belief that they can win back the Spanish league title from archrivals Real Madrid.

"We still we have a way to go, but we can be satisfied. We worked really well," Rijkaard said.

They start their La Liga campaign in just two weeks with a trip to Racing Santander late August.
