Arsenal have suffered an injury setback ahead of their Champions League clash with PSV.
Brazilian winger, Gabriel Martinelli, is likely to miss the game after missing the training session on Tuesday.
Martinelli was pulled out in the first-half of Arsenal’s hard-fought 1-0 win over Everton at Goodison Park at the weekend.
He was taken off and replaced by Leandro Trossard after just 24 minutes.
Arsenal will begin their Champions League group stage fixtures against PSV on Wednesday.
However, Mikel Arteta’s side are yet to provide an official update on the Brazilian’s fitness.
