Hi Guillem, Do you think Atheltic Bilbao will be able to keep hold of their star players this summer? Fernando Llorente, Iker Muniain, Javi Martinez and Ander Herrera would improve any Premier League side and have all been linked with moves away. What are the chances of any of them leaving and in particular, do you know how strong Manchester United's interest is in any of them? Thanks. Shane Farrington
GUILLEM SAYS: Martinez would be a very expensive signing - 40million plus. That means you really have to think of him as the main star of your team. Barcelona are looking at him as a centre back possibility or he can play central midfield. If someone is willing to spend that kind of money - and that's a big if - then he is most likely to stay in Spain. Llorente will have a year left on his contract, but he is dragging his heels on signing a new deal and there is an opportunity for English sides to go and get him. He's had offers in the past from Spurs and Liverpool were in touch with before they signed Fernando Torres and then opted for Andy Carroll. And Fulham could have got Llorente for £1.5million at one stage but at the time - I won't say who the manager was - they didn't think he was good enough. He is most likely to leave. Ander Herrera will stay, Martinez will be sought by Barcelona or Real Madrid and Iker Muniain - who will be a superstar - will probably stay another year.
