Reece Oxford has completed his transfer from West Ham to Augsburg and signed a four-year deal with the German club.
The fee is undisclosed but believed to be in the region of £2.1 million.
The 20-year-old – who was hailed as one of the brightest young prospects in English football when he made his Hammers first-team debut at the age of 16 – spent the second half of last season on loan at the Bundesliga side.
“I am very happy that a solid change to Augsburg has worked out,â€ said Oxford.
“I have felt very comfortable in the city and the club for the past six months and would now like to take another step in my development in the Bundesliga.â€Embed from Getty Images
Oxford became West Ham’s youngest first team player when he made his debut in the Europa League in 2015 at 16 years and 198 days, before making his Premier League debut the following month.
He dominated Mesut Ozil as West Ham beat Arsenal 2-0 on the opening weekend and was expected to go on and establish himself in the side.
However, he made just 17 first team appearances in all for the Hammers, his last coming in January 2018 against Crystal Palace.
Augsburg managing director Stefan Reuter said: “We are glad that we can sign a player in Reece who already knows the club and knows which values â€‹â€‹we live in Augsburg.
“We are convinced that he will strengthen us in the coming years.â€
