The Wales coach insists his team will target a positive result on Tuesday against Group A's second-place side, as they travel to Osijek on the back of victory over Scotland
Coleman's side go into the game against the second-place team in Group A as underdogs but the former Fulham manager is determined to build on the 2-1 victory over Scotland.
The 42-year-old believes that Wales must expect themselves to take points off of the top countries if they wish to have a chance of qualifying for future major tournaments.
"We've done well on Friday, a magnificent result, a great performance, but that's then - Tuesday is coming up now and we have got to go and perform and take something out of the game and we will do that if we concentrate on our performance first and foremost," Coleman told Sky Sports.

"You have got ten games in qualifying and you have got to take something, as hard as it is maybe, home and away you have got to take something out of the game.
"There is no better feeling than going away with your country to a tough place against a good team and you get something and you perform.
"That is what really gives you that confidence and that is what we must do."
