Coleman told Kolarov to focus on his own game when they Serb questioned Wales' style going into the World Cup qualifier.
He said: "We were quite surprised at how easy it was against Wales.
"We knew they would try to get the ball out to Bale and counter attack but we expected them to be difficult to break down. As it was we scored six and could have scored more.
"We expected a bit more from Wales definitely but the main thing was for us to win at home. I was really happy with my free-kick but I had two more I could have done better with."
