Sims is a young winger who fits the Red Bulls' style of play and will try to help them make a push to MLS Cup in 2019.
INTERNATIONAL: Sims has appeared for England at several youth international levels, most recently in the 2019 Toulon Tournament against U-23 competition.
OUTSIDE MLS: Sims made his Southampton debut in the Premier League in November 2016, earning a first-minute assist on the eventual game-winning goal against Everton. Weeks later, he earned a start for Southampton in a Europa League match, marking his first venture in European competition. Sims has made 26 appearances across all competitions for Southampton’s senior team, including 20 in the Premier League, recording two assists in 573 league minutes. Sims went on loan to Reading in the Championship last August, recording three goals and four assists in 18 appearances, but rejoined Southampton for the second half of the 2018-19 season under new manager Ralph Hasenhüttl. Sims earned consistent minutes during the stretch run, appearing in seven of the final nine matches of the season and helping Southampton survive the relegation battle to remain in the Premier League.
