Arsene Wenger has sent Andre Santos on loan to Gremio to rediscover his form, having lost confidence due to the lack of first-team opportunities.
The Brazilian left-back completed a temporary move to his homeland just before the transfer deadline, and Wenger hopes the 29-year-old full-back can return to form during his loan switch.
"He moved because he'd lost a bit of confidence and he needs to play," Wenger said. "He's a guy who's a very good football player, but he didn't get enough games."
Santos was out-of-favour at Arsenal, with Kieran Gibbs Wenger's first-choice at left-back. With Gibbs picking up a long-term injury, Santos could be forgiven for thinking that this was his chance to cement his position in Arsenal's first-team.
But Wenger dived into the transfer market to find a replacement, having signed Nacho Monreal from Malaga and in turn, pushing Santos further down the pecking order.
Wenger believes a stint of playing games back in Brazil will be good for Santos' confidence, and the French tactician is refusing to rule out Santos having a long-term future at the Emirates upon his return.
"He's more at ease in my opinion on the left of midfield, where there's a lot of competition," said Wenger. "He will be back at the end of July, and of course he can have a future at Arsenal.
"That depends as well on the ins and outs during the summer."
