Gabriel Jesus didn't report for Arsenal training on Wednesday morning. The striker looked to be in some discomfort during the Gunners' 3-2 home win over Liverpool on Sunday after Kostas Tsimikas caught the Brazilian with a flailing arm in the second half.
Though he continued for a while after, he was eventually brought off. There's no official reasoning as to why he missed Wednesday morning's training session, but it's expected to be linked to the suspected injury worry he had at the weekend.
Oleksandr Zinchenko is another who didn't make it out onto the training pitch following his recent injury setback. The Ukraine international was as passionate as every other Arsenal fan in the ground on Sunday, but it looks as though Thursday will come too soon for him to return to the field.
