Mikel Arteta warned that Arsenal may need to be careful with star defender Gabriel Magalhaes in the coming weeks, after the centre back picked up a knock while on Brazil duty.
Gabriel had been a surprisingly omission from Arteta's team sheets at the start of the season, with the Spaniard choosing Thomas Partey at right back with Ben White partnering William Saliba in the middle.
Against Manchester United, however, the Brazilian was back in partnership with Saliba for a 3-1 win for the Gunners in a dramatic clash at the Emirates.
