Arsenal defender Cristhian Mosquera is intensifying his recovery from a hamstring injury sustained on August 31 during a 1-0 victory against Aston Villa. Mosquera, who has been sidelined since, is utilizing Valencia's training facilities in Paterna, Spain, to regain fitness. He was reportedly accompanied by a rehabilitation coach from Valencia, a club where his brother Yulian Mosquera remains in the youth academy. Mosquera is expected to rejoin Arsenal's match-day squad after the international break, potentially for the October 10 fixture against Leeds United. His return is crucial as Arsenal also manages other defensive injuries, including Ben White's groin issue and Jurrien Timber's ongoing recovery from a groin injury, with William Saliba also targeting a December comeback. Coach Mikel Arteta hopes these players will bolster the squad for upcoming tough fixtures.
