Soccer-Messi injury stokes Laporta's club v country worries

MADRID, Sept 14 (Reuters) - Barcelona's Argentina forward Lionel Messi is a doubt for Sunday's Primera Liga match away to Osasuna after returning from international duty with an injury, the club said on Friday.

Messi did not train with the rest of the squad due to a "significant strain to a thigh muscle in the right leg", Barca said in a statement on their Web site (www.fcbarcelona.com).

The 20-year-old inspired Argentina to a 1-0 friendly win over Australia in Melbourne on Tuesday.

To avoid aggravating the injury he has been declared a doubt for the trip to Pamplona, adding fuel to president Joan Laporta's demands that national teams should compensate clubs for the use of their players.

"The clubs pay the players' salaries and they should receive compensation, from either FIFA or from the national federation who call up the player," Laporta was quoted as saying on the club's Web site.

"The clubs should receive a proportion of the players' wages...and part of the income generated from the games which they dispute, especially in friendlies.

"From the presidency of UEFA there is a willingness to resolve the problem. It's not in their interests to go against it. Barcelona proposed to the G-14 a year of reflection on the issue to try and reach agreement. I sit on different commissions at FIFA and UEFA and saw it advance very slowly.

"As of now they have not put forward any concrete solutions and so I believe the clubs have to start to act."
