One up front? Two up front? It makes no difference for Spain coach Vicente del Bosque.
Spain knows it will face a packed defense when it hosts Slovakia and coach Vicente del Bosque reckons patience is the key - not how many strikers he uses.
"It's true, we are expecting a team who will play with six men always behind the ball, which will make it tough for us to find space," he said. "This is what we have to be prepared for. I think it will be better for us. I hope it is this way and we dominate the game, that we control possession, that we have sufficient patience, and the ability to overcome them.
