Boss Steven Gerrard believes Douglas Luiz will understand why Aston Villa rejected Arsenal's deadline-day moves for him.
The Gunners had three bids turned down on Thursday, the last being around £25million.
Midfielder Luiz, who scored against Arsenal in Wednesday's 2-1 defeat at the Emirates, is out of contract next summer but Gerrard expects him to refocus quickly.
He said: 'I've got confidence he'll understand the situation and the club's decision, we didn't want to lose a very important player and a top player so late in the window.
