Arsenal manager Unai Emery says he won't rush the return of defensive pair Hector Bellerin and Kieran Tierney.
The Gunners meet Watford on Sunday.
On the possibility of Bellerin and Tierney returning, Emery said: "Not yet. It depends on their progress in the next weeks.'
"Maybe also we can decide for them to play in the U23s, maybe they can take confidence, better rhythm and after be ready to play with us 100%.
"We need to look at the next steps in each training and also if we decide to play with U23s. They did this week the first time training normally with us. We want the next week to take the normality training with us.
"After that week we can decide how they are to start playing with the Under-23s and with us."
