Barnett signed for Wrexham in 2022, when the side was based in the National League. He only managed 12 appearances in the club's first season under Hollywood ownership. The right-back grew into the team during their stay in League Two, managing 37 appearances, and contributing two goals and four assists.
It seems the harder the league, the more he thrives, and this season he has truly come into his own. Playing at right-wing back in Wrexham's 5-3-2 formation, Barnett has already levelled his goal contribution tally from last season, and with the way he has been playing, Wrexham can consider it a massive coup to keep him at the club for the next three years.
