I'm not scoring because Barca put me on the wing, says Henry

"I'm not used to playing on the wing after spending eight years at Arsenal as a striker. Now I play a different role," he said.

"It's the coach who decides the system and I don't have a problem with it."

However, Henry's recent body language suggests he is less than enamoured of his wide role at the Nou Camp. He has scored six goals in 18 appearances for the Catalan club.

The former Arsenal striker appears to have gone full circle. After France's 1998 World Cup triumph he moved to Juventus, but fell out with the Italian club after being asked to play on the wing.

Arsene Wenger proved his saviour when he brought him to Arsenal for £10.5million in 1999 and turned him into a world-class striker. He left Arsenal as the club's all-time league goalscorer with 174 goals and all-time goalscorer in Europe with 42 goals.

Henry's strike partner Samuel Eto'o will be rested for the trip to face Real Zaragoza on Saturday to allow him to recover from a thigh muscle strain.

Leaders Real Madrid are likely to have their Dutch striker Ruud van Nistelrooy and Argentine defender Gabriel Heinze back from injury to play away to Real Betis on Saturday. Dutch midfielder Wesley Sneijder is back from suspension.

Betis' Argentine striker Mariano Pavone is looking forward to testing himself against Iker Casillas.

"The goals appear much smaller when he is in them," Pavone said. "Real don't defend in numbers, which means you get chances but you have to take them, because the slightest error you make can be costly."

Getafe midfielder Jaime Gavilan will miss the match at home to Valencia on Sunday. After a clash of heads during Wednesday's UEFA Cup match away to AEK Athens, he fell head first on to the pitch and had to spend the night in hospital. He will be out for a week.

Sevilla visit Espanyol on Saturday without suspended full back Daniel Alves and Mali midfielder Seydou Keita.

Their Spanish international centre back Javi Navarro, who has not played a game all season, looks set for a longer period on the sidelines after club doctors said his recovery from a knee injury was taking longer than expected.

Atletico Madrid will be without suspended Colombia defender Luis Perea and have a doubt over Portugal winger Simao Sabrosa, who has picked up a thigh injury, for the visit of Athletic Bilbao on Sunday.
