Manchester United boss Jose Mourinho explained his reaction to Marouane Fellaini late winner when he kicked over a case of water bottles.
"Relief. We didn't play to be in trouble until the last minute. I was frustrated we couldn't score. My players were very tired at the end. That's what I want. Without David de Gea's save, no winning goal. We qualified. We did it.
"He is the best goalkeeper in the world. If our ambitions are to be the best goalkeeper in the world, we have to keep him.
"Realistically to be in the last 16 is an achievement, not a big one or a fantastic one, but an achievement. There are better teams than us. Teams with more quality and realistic ambitions. When a team arrives in the quarter-finals, anything can happen."
