Arsenal edged past Bournemouth with a 2-1 win at Vitality Stadium on Monday to reach FA Cup fifth round.
Bukayo Saka scored the opening goal in the 5th minute before Eddie Nketiah made it 2-0 in the 26th minute.
Arsenal had a late scare when Bournemouth substitute Sam Surridge scored a goal eight minutes to stoppage time.
But even that scare didn’t stop Arteta’s more organized side from reaching the fifth round in the FA Cup, thanks to the fine play from Willock and Matteo Guendouzi as well as Saka’s and Nketiah’s goals.
The only blight to an otherwise excellent game for the Gunners was when Shkrodran Mustafi was injured in the second half and had to be taken off on a stretcher.
