wait a minute! I checked Estoril players' list and he isn't there!Are you sure?
He is in Estoril, he is going to play there - unless he gets injured again, of course, but he said his back feels better. He plays the qualies, maybe what you saw was just the entry list for the main draw? I don't think there is a list for the qualies yet, they can still sign in.
I've seen on the French blog he wants indeed to play the qualies in Rome and Hamburg after Estoril. I thought it might be close with his ranking, but he must know what he's doing.
So if you're going to Rome for the qualies, lady_mont, maybe you can see Mathieu again there!
