West Ham defender Reece Oxford has signed a new four-and-a-half year deal.
The Hammers said the 18-year-old turned down interest from clubs including Manchester United, Manchester City and Arsenal.
Oxford was the second youngest player to start a Premier League match when he made his competitive debut against Arsenal, aged 16, at the start of last season and starred in a 2-0 win at the Emirates Stadium.
"I just want to kick on now," he said.
"There was a lot of speculation about my future but I am happy it has been done and I can get back to football.
