Mikel Arteta delivers worrying Bukayo Saka injury update with Arsenal staff 'concerned'

Mikel Arteta has said that Arsenal medical staff are "a bit concerned" over an injury sustained by Bukayo Saka during Wednesday evening's Champions League match with Bayern Munich. The Englishman lasted just 10 minutes during the clash at the Allianz Arena before he fell to the ground writhing in pain after playing what looked to be a routine pass, his arm in the air signalling he needed treatment. The 25-year-old was also spotted clutching at his thigh as medical staff rushed onto the field to assist him.
