Calum Chambers took to social media to wish Alex Oxlade-Chamberlain a happy birthday as Arsenal gear up for Sunday’s Premier League trip to Crystal Palace.

The England midfielder turned 22 on Saturday as Arsene Wenger’s men completed their final preparations for their trip to Selhurst Park.

Oxlade-Chamberlain has enjoyed a bright start to the season and was in fine form as Arsenal beat Chelsea 1-0 in the Community Shield earlier this month, scoring the Gunners’ first-half winner at Wembley.

And Chambers posted a picture of the duo in karaoke action on his personal Instagram account on Saturday morning to wish his team-mate all the best.

Chambers shared the picture above and wrote: “Happy birthday to the main man @alexoxchamberlain. Maybe one day we can fulfil our potential as singers! 🎉🎤”

Arsenal are looking to notch up their first Premier League win of the season after their shock 2-0 defeat by West Ham United in their opening game at Emirates Stadium last weekend.
