Central defender Gabriel featured regularly throughout his first full season at the club, and claimed his first Gunners goal in the home win over Bournemouth just after Christmas.
A committed, robust defender who is also strong in the air, his headed effort from Mesut Ozil's corner was also his first-ever goal in European football, having not registered during one and a half seasons with Villarreal in Spain.
But it's his defensive qualities with which Gabriel has most impressed since signing for Arsenal during the winter transfer window in 2015. He brings strength and a fierce competitive spirit to the back line, and indeed the Gunners didn't lose any of the first 11 Premier League matches in which he completed 90 minutes.
A consistent performer, he featured alongside either Laurent Koscielny or Per Mertesacker in the heart of the Gunners defence during every month of the campaign last season.
Gabriel (full name Gabriel Armado de Abreu but also referred to as Gabriel Paulista) was called up to the Brazil national team in March 2015, but was an unused sub for the match against Chile at the Emirates Stadium.
Also able to operate at full-back, Gabriel started his career with Vitoria in Bahia, Brazil and won two regional league championships with the team, in 2010 and 2013. He was also named best central defender in the Bahia league in 2012 and 2013.
