Juve are ahead of Milan in the Serie A standings by one point.
Ibra said: "There are six games in the League and we will do everything to get maximum points. We are here and we must remain focused and prepare well for each game.
"We have one point less, but if we concentrate, we can take back the lead. Games against Catania and Fiorentina, with hindsight, are ones we could have won. It is important not to repeat those mistakes and to do our best in upcoming games. Hopefully we will be back on Sunday and I will score."
