The £35m signing penned a five-year-deal worth around £120,000-a-week with Jurgen Klopp’s side on deadline day.

He was unable to meet up with most of his team-mates, however, until yesterday (September 6) due to England’s World Cup Qualifiers against Malta and Slovakia.

But he looked happier than ever donning the famous red jersey in a clip posted to his Instagram today.

The Ox is seen hugging Klopp as he makes his way into training.

He then starts going through the gears on the pitch, before undertaking his media responsibilities.

The video ends with Oxlade-Chamberlain standing proud with a huge grin to the camera.

More than 124,000 people have seen the clip, but it received a mixed reaction from fans.

“Ox about to take his career to new levels,” one wrote.

Another added: “Can’t wait to see you play for us… sooo happy!”

A bitter Arsenal fan wasn’t as appreciative, commenting: “Heartbroken.”

The 24-year-old could make his debut for the Kop against Manchester City on Saturday (September 9).
