Speaking to Sky Sports, Van Nistelrooy said: "I have to say we had some luck as well, I am so happy for Casemiro though and [Alejandro] Garnacho and Bruno [Fernandes]. Five goals but the chances against West Ham and Fenerbahce, we created so much and couldn't finish., All of a sudden we had some luck on our side and that made it a great night.
"It is always the target to react and attack. The reaction of players after the Leicester goals were excellent and they deserve the credit. I am glad the crowd go home happy."
