Arsenal manager Unai Emery has confirmed Kieran Tierney will play against Standard Liege in the Europa League on Thursday.
Tierney made his debut for the club last week against Nottingham Forest, but he missed Monday's draw with Manchester United and was withdrawn from Scotland's upcoming qualifiers at Arsenal's request.
However, Emery says the left-back is ready to go.
"After his injuries, each step is important to be consistent," Emery said.
"He didn't play in Manchester because he had some more problems. Not important, but the doctor told us it's better to be here working alone and preparing for the match tomorrow.
"If we are taking precaution with him it's also important that, with the national team, we are thinking it's not the moment to go with them.
"For the next matches, I think he's going to be ready to play with us and to play with them.
"Now he's going to play tomorrow and also hopefully he can be complete physically, complete tactically, with the performance we need."
