Arsenal manager Mikel Arteta has sent an encouraging message to Gabriel after the center-back missed out on a place in the Brazil squad for the World Cup.
The center-half has been in outstanding form for the Gunners this season alongside William Saliba.
However, he was not noticed by Brazil coach Tite, who preferred others in that position over Gabriel.
"For Gabi, it's a disappointment," Arteta told reporters before Arsenal's EFL Cup loss to Brighton on Wednesday.
"But when you look at the squad that they [Brazil] have and the experience they have in that position, you have to understand that and it's another challenge for him.
“He needs to be ready for the next one, he needs to improve and carry on with the good things that he's been doing."
