Lucas Perez scored his first Arsenal goals as they reached the fourth round of the EFL Cup with a comfortable win at Championship side Nottingham Forest. Granit Xhaka's stunning 30-yard strike gave the Gunners the lead. Former Arsenal striker Nicklas Bendtner shot wide for Forest before Lucas doubled Arsenal's lead from the penalty spot after Chuba Akpom was fouled. Lucas then rounded the goalkeeper for his second before Alex Oxlade-Chamberlain drove in a late fourth. Bendtner, meanwhile, was making his first appearance against his old club, where he spent nine years at between 2005 and 2014.
