England international Oxlade-Chamberlain will feature in a TV advertising campaign for the pay-TV broadcaster and appear as a ‘regular guest’ on the channel for three years.
The exact terms of van Persie’s deal are yet to be confirmed but they are likely to be similar to those of his former Arsenal team-mate.
Oxlade-Chamberlain said: “I am very pleased to be named as a BT ambassador and to feature in the adverts and as a guest for BT Sport. As a young player, I hope I can bring some real insight into the Premier League, as part of the BT Sport team.
Simon Green, head of BT Sport, added: “We are thrilled that Alex has agreed to sign up for BT Sport. Alex is emerging as an international star, having broken into the senior team aged just 18.
“His hard work and dedication to improvement has already taken him to great heights and serves as an inspiration to young football fans that if you are good enough, you are old enough.”
