He told the media:"I don't know. Tomiyasu looks pretty serious from his reaction straight and what he said to me, but obviously, it's very early. Willy? I don't know, he had some discomfort and could not continue so we had to take him out."We've been carrying injuries throughout the season. We had Emile out for four months, Jesus for four months, Thomas for a month and a half, Alex for two and half months, Eddie for a month and a half. We had quite a lot of injuries already, but we dealt with them."The disappointment is not going to go away it's there now. But there's also clarity. It's 11 games to go now and we have a final against Crystal Palace. We have to recover and put all the focus there and win."The Gunners will next face Crystal Palace in the Premier League on Sunday, March 19, before the players leave for the international break.
