The Gunners face Molde in the UEFA Europa League on Thursday and may be without both players
Mikel Arteta has confirmed Willian and Bukayo Saka picked up injuries during Arsenal’s 0-0 draw with Leeds United.
Nicolas Pepe stole the headlines from Sunday’s Premier League stalemate after being sent off for headbutting Ezgjan Alioski, but it was far from the only bad news the Gunners took from the match.
Willian did not appear for the second half and Saka failed to finish the match - being replaced by Ainsley Maitland-Niles - after entering the field from the bench in the 57th minute.
