Arsenal have been dealt a fresh injury concern ahead of their Champions League quarter-final second leg against Real Madrid, with Ben White left out of the squad for Saturday's Premier League clash with Brentford.
White, 27, was a surprise omission from Mikel Arteta's matchday 20, with the Arsenal boss confirming the defender 'felt something again post-training yesterday' and was not risked.
It is unclear if the issue is related to the knee injury that kept him sidelined for 25 games earlier this season.
