Liam James Rosenior (born 9 July 1984) is an English retired professional footballer who played either as a full-back or winger. He is the son of former player and manager Leroy Rosenior, and spent time on loan at Torquay United, where his father was manager, during their promotion season in 2003–04. He also played for Bristol City, Fulham, Reading, Ipswich Town, Hull City and Brighton & Hove Albion.
Born in London, Rosenior started his career with Bristol City as a promising midfielder. Arguably his best moment came when he scored the second goal in a 2–0 victory for Bristol City against Carlisle United in the 2003 Football League Trophy Final at the Millennium Stadium. This would prove to be his last appearance for City as Fulham soon snapped him up.
On 22 September 2004, Rosenior was sent off on his Fulham debut in a 4–1 Carling Cup second round win at Boston United when he received a second yellow card in injury time for diving. He would not make his Premiership debut for the club until 22 December when he impressed in a 1–1 home draw with Manchester United, earning him the Sky Sports Man of the Match award. Rosenior's first season at Craven Cottage would end as it began when he was sent off in a 3–1 win at Blackburn on 7 May for pushing over Robbie Savage in the 70th minute. Rosenior soon became popular amongst Fulham fans due to his Afro hairstyle. During a match against Manchester City Rosenior made a seemingly impossible goal line clearance while the score was at 1–1, Fulham going on to win the game 2–1 with Steed Malbranque scoring in the last minute. Rosenior later told reporters that he was able to clear the ball in that manner due to his Afro hairstyle. He scored once for Fulham, in a League Cup tie against Lincoln City on 21 September 2005.
