SPAIN ON SERGIO
Hi Guillem, What is the view of Sergio Busquets in Spain? Is he held in high regard or do some people believe he is overrated and a bit too controversial? Thanks, Sam Richardson (Tottenham fan) GUILLEM SAYS: Sergio Busquets is seen as the best central midfielder in the world - and nobody in Spain will argue with that. Some Real fans may say he's too controversial sometimes but in the way he plays nobody plays better in that position, nobody in the world. Nobody plays in front of the back four, starts attacks and fills gaps like him.

PIQUE'S NEXT PAL
Hola Guillem, Who do you see being the long-term central-defensive partner of Gerard Pique at Barcelona once Carles Puyol retires? Thanks, David Stockton (Man United fan) GUILLEM SAYS: I don't think they have a long-term replacement at the club. Marc Bartra is more like Pique and I don't think they have another centre back of that stature so they will need to buy to strengthen.

PROBLEM POSITIONS
What positions do Valencia need to strengthen to move up the league table and push for a European spot? Thanks, Marcus Smith (Arsenal fan) GUILLEM SAYS: Central midfield is a problem. David Albelda can not play three games in a week but he settles the team. Certainly Tino Costa and Ever Banega don't work consistently enough but I think it is more that the changing room is full of players who don't care enough for Valencia.

BIELSA ON HIS WAY?
Hi Guillem, You often speak about Marcelo Bielsa on Revista. Do you think his position at Athletic Bilbao is becoming untenable and who do the club see as a potential replacement? Cheers, George Marquez (Real Zaragoza fan) GUILLEM SAYS: It's clear a lot of problems are to do with Bielsa. It is not only about Llorente playing or not. Aduriz is having a great season, he's scored 13 goals and Llorente only scored nine at this stage last season. The problem is the central midfield isn't settled, they lose lots of balls, they try to do everything at high speed like they did last season, without being so effective. He may stay until the end of the season but I don't think he'll stay any longer.

KID GLOVES
Who do you think the best young goalkeeper in Spain is? Surely it has to be Thibaut Courtois? Thanks, Ben Marshall (Man City fan) GUILLEM SAYS: The problem is there are so many good goalkeepers in Spain, including Roberto, Thibaut Courtois and Kiko Casillas at Espanyol, who played against Real Madrid and is a good goalkeeper.
