In 2007–08 West Brom reached the FA Cup semi-finals for the first time since 1982, but lost 1–0 to Portsmouth at Wembley Stadium. The crowd of 83,584 was the highest ever for an FA Cup semi-final. A month later they won a third promotion to the Premier League by winning the Football League Championship. However, the next year they were relegated again and Tony Mowbray left to manage Celtic. Roberto Di Matteo was appointed as the new manager and after a successful season Albion were yet again promoted to Premier League.
