Diego Costa scored four goals as Atletico Madrid embarrassed La Liga rivals Real Madrid 7-3 Friday in a pre-season friendly at MetLife Stadium. Costa had a hat-trick by halftime and added one more goal before he was sent off in the 63rd, when both teams were reduced to 10 men after a testy shoving match. "We started the game very poorly. In a top-level match such as this, we had a very bad start, Real Madrid coach Zinedine Zidane said. "The players are well aware and they're disappointed. "We don't need to dwell on it, this is a pre-season game. They were better in every respect and that's all there is to it."
