Osasuna midfielder Krisztian Vadocz is recovering from a mild case of the H1N1 swine flu virus and has been isolated from the rest of the squad.

"The news surprised me because I feel in perfect condition," the Hungary international was quoted as saying. "I am bored in my room and looking forward to getting back to training with my colleagues."

Last week, Vadocz underwent tests after suffering from a temperature and a cough while at the club's pre-season training camp in Jerez, in the south of Spain.

Meanwhile, an African player in the world's biggest youth football tournament - the Norway Cup - has also come down with swine flu, and four other participants are also suspected of carrying the virus.

Organisers had taken numerous measures to limit the chances of an H1N1 outbreak including a ban on handshakes.

"We had to change routine and now just say 'hello' to each other, run past each other, but we don't shake hands," Terje Lund, deputy chief of the Norway Cup organisers, said.

The tournament has attracted 30,000 players, aged 10 to 19, from 50 nations.

Lund said the tournament was "lucky" that the sole confirmed case of the H1N1 flu, which has killed 800 people worldwide, was spotted early and that the player was isolated from others. The other players suspected of the flu are from different teams.

"I would expect more cases (to occur) but we are as prepared as we can be," Lund said.
