Francesco Farioli, coach of FC Porto, talks about the injury suffered by Diogo Costa, revealing physical problems in some players and talks about the evolution of Samu, who scored twice against AVS: Diogo Costa injury «He is positive, but tomorrow he will have an MRI so we can have a clearer picture of the situation. It’s muscular, but we hope it’s not serious.” Problems on the wings “We had some problems with the full-backs. Francisco (Moura) had the same problem as Alberto with Alverca, Pablo (Rosario) wasn't very well today from a physical point of view and Martim had inflammation in the pubic area.” Samu said the 1-0 was a criticism of those who say they are clumsy «The first goal is a movement that he is working hard on. In the last game, in the second goal, he did an important job receiving and holding the ball. It was important, just like today. Samu is a young man with a lot of potential and someone who really wants to improve. He’s a goalscorer and I see him improving a lot in different areas.”
