Juventus will likely have to contend without the services of Arthur from the start against Parma this weekend after the Brazilian had to be replaced in the first half in the Bianconeri's midweek match.
In the 1-1 draw at home to Atalanta, Arthur picked up an injury to his thigh and was subsequently replaced by Adrien Rabiot. It isn't a serious issue and although there is an outside chance he could be fit for the Parma game, head coach Andrea Pirlo is unlikely to take an unneeded chance on his fitness.
Rabiot will come into midfield in his stead.
Pirlo opted to switch things to a back four for the Atalanta match, and will probably keep it that way for the Parma fixtures, perhaps with Alex Sandro coming in at left-back in place of Danilo.
Juan Cuadrado, arguably Juve's best player of the last few weeks, will feature at right-back with Leonardo Bonucci partnering Matthijs de Ligt in the centre of the defence.
PIrlo may opt for some rotation in midfield, but it is important that Juventus start to find some consistency in their performances. So, Federico Chiesa, Rodrigo Bentancur, and Weston McKennie could all start again in midfield.
Neither Cristiano Ronaldo nor Alvaro Morata found the back of the net against Atalanta, with the former missing a penalty and the latter missing an open goal with a comedy failed backheel.
But, they did link up fairly well at times, so will probably feature in the starting XI again, with Paulo Dybala settling for a place on the bench.
