Juventus play host to second placed Napoli on Sunday evening in what looks to be the biggest game of the season for both sides.
Whilst Wojciech Szczesny's transformation to a decent goalkeeper has been impressive, there's only one choice between the sticks for Juve in such an important match.
Gigi Buffon may have come under fire for his comments about referee Michael Oliver, but there's no doubt his experience and talent will be crucial for Juventus.
- Alex Sandro12
Losing Leonardo Bonucci in the summer meant Juve were forced to adjust their defensive shape for this season, and it's safe to say they've continued their reputation of having a formidable backline - conceding the fewest goals in Serie A this season.
They'll look to Alex Sandro to provide width from left back as he attempts to add to his tally of four goals and four assists so far this season.
It'll be interesting to see which way Allegri decides to set up his midfield. The three looks more likely than a 4-4-2 though, as he'll want to make sure he isn't outnumbered by Napoli's 4-3-3 in the middle of the park.
Khedira and Matuidi will provide a function and legs. Matuidi's versatility will be key as Alex Sandro goes forward - the Frenchman will have to plug the gap left by his left back - while Miralem Pjanic will pull the strings.
- Douglas 11
With 78 goals in Serie A this season, Juventus boast the second best attack in the country.
Gonzalo Higuain will be keen to net against his former club, his tendency to miss big chances in big games is the main criticism of the striker, but with Douglas Costa cutting inside and committing defenders, there will be space for him to exploit.
Expect Mario Mandzukic to start again too - with no room for Paulo Dybala.
