Manchester United defender Lisandro Martinez could have a new role against Arsenal at the weekend.
The Red Devils will have to do without Casemiro for their top of the table clash at the Emirates Stadium.
The Brazilian is suspended after picking up his fifth yellow card against Crystal Palace on Wednesday.
Per the Daily Express, one option for manager Erik ten Hag is to bring Martinez up into midfield.
Luke Shaw would then slot in at center-half alongside Raphael Varane, as he did against Manchester City last weekend.
The other option is to play Fred or Scott McTominay in Casemiro's position, which has not always been a success.
