"We want to fight to go to Europe and we did it as a team today. We fought together to win the game."
On his two goals, he added: "I expected he (Noni Madueke) would pass because we are close friends and team-mates. It was a very good assist from him.
"Every time I score VAR will try to interfere but I was very happy this time."
