What's the club's transfer strategy?
“We have no language barriers with [Paulo] Fonseca. We are working together to find the best solutions.
"We want to keep hold of our best players as long as possible. We want to make them develop and keep them for as much time as we can and be competitive.
“Fonseca is the fifth coach I'm working with, I know him very well. I identify myself in his ideas, an offensive and dynamic football. His ideas are the right ones for this club.
“I can't say how many operations we'll do in January, we are working to make the best deals.
“I repeat this is a medium to-long term project and we are working to make the team more competitive."
