Gabriel Martinelli was absent from Arsenal team training ahead of their Champions League round of 16 second leg against Porto on Tuesday but both Jurrien Timber and Takehiro Tomiyasu were involved.
Martinell missed the win over Brentford on Saturday due to a foot injury sustained against Sheffield United earlier this month and was not part of the Gunners’ open training session ahead of the visit of the Portuguese side.
But Timber was seen back in training having not played since the opening game of the season because of an ACL injury.
Tomiyasu also took part after missing the last five games through injury.
Mikel Arteta’s men trail 1-0 in the tie following their first leg defeat in Porto.
