Barca had trimmed Real Madrid's advantage back to six points prior to last weekend's matches, but with Frank Rijkaard's men being held 1-1 at Sevilla and Real hammering Real Valladolid 7-0, everything now seems to favour the champions.

Not only do they boast that eight-point lead, but Bernd Schuster's troops have a superior goal difference of plus-eight and also beat Barca 1-0 at Camp Nou in December - a fact that could yet prove key with Real having won the title last season because of their better head-to-head record against their arch rivals.

Despite all that, Henry is remaining positive, pointing out that last year Barcelona themselves held a similar advantage over Real at this stage of the campaign.

"We have to have a winning mentality. We have to believe in this team, everything is possible. If Madrid achieved it, then so can we," the France international said.

"Since the defeat against Real Madrid we haven't dropped many points, in fact we've only drawn two matches. We can win everything but it'll be difficult. We have to continue working."

As for his own form, Henry admits he has sometimes had to play a slightly different role at Barca to the one that saw him become the record goalscorer with previous club Arsenal, who he left last summer.

"I'm never happy with my performance. You can always do much better," said Henry, who has struck six league goals for Barca.

"The truth is I'm not used to playing wide. I played at centre forward with Arsenal for eight or nine years but if the boss asks me to drop wide I do it without any problems."

Meanwhile, Barca vice-president Ferran Soriano has reiterated the club's stance over Ronaldinho by insisting the Brazilian playmaker is not on the market.

"Ronaldinho is not for sale. Neither do we want to sell him, nor does he want to leave. He is one if us," said Soriano.
