The Catalan's coach Frank Rijkaard has advertised that there will be changes to the sides that beat Levski, and also Osasuna 3-0 on Saturday, as he continues to rotate his squad but he has an embarrassment of riches at his disposal.

"But whoever is playing and whoever we are playing, we are always going to play the same way, with the same calmness and the same enthusiasm," said World Player of the Year Ronaldinho on Wednesday.

"It's possible that overall we are even better than last year," added Barcelona playmaker Andres Iniesta, reflecting the upbeat mood in the dressing room despite the fact that no one has a guaranteed starting place.

In the same fixture last season, Racing held the Spanish giants to a 2-2 draw and that would be considered an excellent result for the hosts this time around as they have yet to score a goal this season.

However, the antidote to Racing's goal drought may have arrived, albeit it a little late, in the shape of the giant Serbian striker Nicola Zigic.

Zigic has been unable to play so far this season because of international commitments but the imposing 2.02-metres tall player finally arrived at the club earlier this week and could play on Sunday.

"I am sure I'm going to adapt very quickly and my aim is to score as soon as possible," advertised Zigic on his arrival on Tuesday.

Sevilla lead La Liga after two matches, on goal difference from Barcelona.

Last season's UEFA Cup winners are one of four teams to have won both their matches but they have a tough local derby at home to Real Betis on Sunday.

"Sevilla have to be the favourites as they are at home but anything can happen in a derby like this," said Betis' Brazilian striker Robert, who is expected to make his season's debut after missing his club's first two matches with back problems.

Adding to the potential problems for Sevilla, their own Brazilian striker Luis Fabiano is doubtful for the match after straining his right hamstring in training on Tuesday.

Getafe travel to Valencia, third and fourth respectively, the latter in buoyant form after their 4-2 win in the Champions League over Olympiakos on Tuesday.

The match brings together the only two other teams with 100 percent records.

Valencia will be without their Italian midfielder Emiliano Moretti, who was sent off last week against Atletico Madrid, and Uruguayan international Mario Regueiro looks set to take his place on the left wing.

Real Madrid lie fifth by virtue of their 4-1 win at Levante on Sunday but that victory over the Spanish first division's bottom club has already been forgotten after the Spanish giants went down 2-0 at Lyon on Wednesday.

"I hope our fans will be patient and accept that we are going to get much better," said Brazilian international Cicinho, who looks set to start at right back at home to Real Sociedad on Sunday.

"They have to have confidence in us because things are going to improve under (Real Madrid coach) Fabio Capello," added Cicinho.

Cicinho's compatriot and World Cup colleague Ronaldo trained with the rest of the Real Madrid first team squad on Thursday, for the first time in almost two months after injury problems with his left knee.

However, Capello might keep the three-time World Player of the Year for another week while he recovers a little more of his fitness.
