The youngster mocked the Hammers winger on social media.
With the Hammers vying to qualify for Europe this season, the mood in the camp seems as strong and Oxford put the former Nottingham Forest winger on blast.
The 17-year-old uploaded a snap of a dodgy-looking slip-on boot which appears to belong to Antonio.
The Irons sit sixth in the Premier League table and it's this type of team spirit which perhaps epitomises the type of jovial atmosphere which manager Slaven Bilic has built in East London - and it might lead them to the Champions League.
Five points separate them and fourth-placed Manchester City, but Bilic's side boast a game in hand, meaning the gap is potentially two points, with two games to go for City - one of which is Arsenal at home.
It has already been a fairytale season for Leicester, who sit on the brink of winning the title, so why can't West Ham get in on the act of defying the odds?
