Derby clashes against Olympiakos are the most important league games, according to Panathinaikos' manager Andrea Stramaccioni.
"It is my first experience out of Italy but I was impressed by the way Panathinaikos treated me. It is a great club and we share the similar ambition. I didn't have much time to work with the squad but we have experienced players and they understand game's importance. We need to be focused and concentrated, because every mistake can cost. I don't personally know Marco Silva but he has done a great work, Cambiasso is an excellent player and helped me a lot when we were at Inter", said the newly-hired Italian manager.
