Inter Milan coach Luciano Spalletti says they must be at their best for the derby with AC Milan.

On the return from international duty Inter will face arch rivals Milan.

“We are in a positive moment, in good shape and playing good football," Spalletti told Sky Sport Italia.

“We've improved in terms of character and that's a fundamental quality when playing such important games. Now we'll see what situations emerge from the break for international duty, but overall we are satisfied.

“We've got to focus only on Milan and then after that we can start to think about Barcelona. The Rossoneri are a strong opponent, play good football and picked up a lot of points in the last few games."
