West Ham United midfielder Reece Oxford has reportedly stalled on contract talks with the London club, alerting Manchester United and Manchester City to his potential availability. The 17-year-old star broke into the Hammers first team at the start of last season, but has since been unable to reach an agreement with the club over a new deal.

The two parties have been in talks for a while, with Oxford only having 18 months left on his current deal. Oxford is considered to be among the most talented teenagers in the country and United and City are known to be among his admirers, according to ESPN.

Oxford made his West Ham debut at the age of 16 years and 198 days in the Europa League qualifying tie with FC Lusitanos in July 2015. He subsequently impressed during his Premier League debut against Arsenal in August that year, when he became the second-youngest player to start a game, at 16 years and 237 days, since the league was rebranded in 1992.

This season, however, the teenager has found first-team opportunities harder to come by. He has only made two appearances in the Europa League qualifiers and is yet to feature in the Premier League.

Despite this, United and City are said to be monitoring Oxford's contract scenario and could make an offer for the player if the two parties cannot reach an agreement.
