Leonardo felt they did enough to win the match.
"My team did deserve a little more. We struggled in the opening 15 minutes, then took control of the game and created numerous chances," he said.
"The second half saw us try to score in every conceivable way and I was impressed with our consistency."
"I am very happy with the experiment. It's not easy to ask a player to adopt a different role, although I did urge him to be a centre-forward when in possession. Huntelaar worked very hard and did well tactically, he had a great game.
"The team is very involved in these decisions that can change the way of playing for several individuals. It's no secret that I discuss it with the squad. At the end of the day I make the decision, but I do talk it over with them.
"The team impressed and it's a shame we didn't win, as we did have more of the ball. I can't deny there is a little bitterness at the result. It's just a pity we couldn't get the goal.
"I am increasingly impressed with the movement of the midfielders. Against teams that mark us closely, they understand that they need to stretch the opposition and today Mathieu Flamini worked very hard in that respect."
