Inter could be without Marcus Thuram for their mouth-watering Serie A showdown with Juventus, Simone Inzaghi has confirmed.

Thuram limped off early after picking up a knock during the Nerazzurri's 2-1 win over Fiorentina on Monday, and has not trained with the squad since.

The France international is Inter's top scorer in the Italian top flight this season with 13 goals, with only Mateo Retegui (20) and Moise Kean (15) netting more in the division.

But Inzaghi, who confirmed Federico Dimarco and Denzel Dumfries will return for the trip to the Allianz Stadium, conceded the reigning champions may be forced to look at alternative options in attack.

"Today, we'll have to evaluate Thuram, we'll see if he'll be able to train with us," he told reporters during his pre-match press conference. "So far, he hasn't done it, he's been working separately.

"We all know the importance Thuram has in our team. At the moment, it's more no than yes. He's a generous guy, and he was available on Monday after a blow he received in Florence, but he lasted 25 minutes and then asked for a change.

"The other strikers are doing well. [Joaquin] Correa is getting over a problem he had since Lecce, [Mehdi] Taremi is fine and [Marko] Arnautovic trained with us yesterday, doing a good job after the problem against Fiorentina."

Inter occupy second place in Serie A and are just one point behind leaders Napoli, who face Lazio on Saturday.

The Nerazzurri are unbeaten in their last five meetings with Juventus in Derby d'Italia, which included an entertaining 4-4 draw in this season's reverse fixture in October.

"We all know what Juve-Inter means and represents for our fans and our club," Inzaghi said. "It's an important match, which comes at a delicate time in the championship.

"We'll have to play an excellent game against a team of quality, which has been strengthened by the winter market and has an excellent coach, whom I respect a lot. They come from three victories in a row. We will have to play a very good game."
