Alexandre Lacazette and Pierre-Emerick Aubameyang have both signed new contracts with Arsenal.

According to talkSPORT, Lacazette has committed to the Gunners until 2022, while his partner has agreed on an extension until 2021. 

It's brilliant news for the club, considering they scored 50 goals between them in all competitions last season. 

Aubameyang was also linked with a sensational move to Manchester United earlier this summer, so for Unai Emery to tie him down is a huge bonus. 

It's also a brilliant end to what's already been a fantastic transfer window for Arsenal. 

Four new signings have already been confirmed - Nicolas Pepe arrives from Lille, Dani Cabellos from Real Madrid, Gabriel Martinelli from Ituano and William Saliba joins from Saint-Etienne.

On top of those four, the Gunners are confident of completing deals for Kieran Tierney and David Luiz before the 5pm deadline. 

The defensive pair will offer a great boost to Emery's backline, one that was significantly weakened when Laurent Koscielny departed for Bordeaux earlier this week. 

It's believed that Luiz an upgrade on Arsenal's former captain, who played just 17 Premier League games in an injury-hit season. 

Tierney, 22, is expected to become a crucial first-team player for the foreseeable future too. However, he's also carrying an injury, according to Celtic boss Neil Lennon. 

"He's still injured and he's rehabbing. He had a double hernia and he still has the Osteitis pubis problem so it's a slow burner that one." 

Despite the Scotsman's problem, after such a brilliant summer transfer window, there will be quite a buzz around Arsenal ahead of Sunday's opening fixture. 

The north London club begin their campaign away to Newcastle and should the likes of Pepe, Aubameyang, Cabellos and Lacazette feature, they will surely be favourites.
