Norwich boss David Wagner says his free-scoring side must moderate their "Wild West" football to continue their recent upturn in the Championship.
The Canaries made it two wins out of two since the German took charge after following up a 4-0 rout at Preston with Saturday's 4-2 triumph at Coventry.
However, Wagner was unhappy they almost surrendered a 3-0 lead at the weekend.
"You have to use your brain in football," the former Huddersfield boss told BBC Radio Norfolk.
"You have to show that you are able to calm the game when you are 3-0 up, to control the ball and this is what we haven't done.
