Arsenal are set to lose Alexis Sanchez this week to Manchester United but it does not appear to have affected the Gunners players one bit.

The home side got off to an explosive start against Crystal Palace with Nacho Monreal heading home after just six minutes from a corner.

Two minutes later Arsenal doubled their lead as Alex Iwobi capitalised on some shocking defending from Palace full-back Timothy Fosu-Mensah.

And the goals just kept on coming as Laurent Koscielny made it 3-0 after just 13 minutes following yet another poorly-defended corner.

Arsenal were not finished and Alexandre Lacazette also got in on the action who bent a smart finish past Wayne Hennessey to make an unassailable 4-0 lead.

After the restart, things calmed down but there was still time for Palace to get a consolation goal courtesy of Luka Milivojevic.

The midfielder latched onto a Christian Benteke knock-down and volleyed a smart effort past Petr Cech but it was too little too late to mount a comeback.

The result keeps Arsenal in sixth place - two points behind rivals Tottenham who have a game in hand against Southampton tomorrow (4pm).
