Smith continued his run in the Leeds side, as the club began to grow in stature. He showed his class in 2001 while helping to lead the Leeds side through the much vaunted UEFA Champions League, though his experience ended on a sour note as he was sent off in the semi-final. The following season saw Smith switched to the right of midfield, his versatility being utilised by O'Leary, as the Leeds manager tried to accommodate new signings. 2001 also saw Smith's break into the England national football team squad. An England youth international at multiple levels, Smith made his senior England debut in May 2001. He did not make the final cut for the 2002 FIFA World Cup, and accepted a position with the England Under-21 side. He scored four goals in a UEFA Cup tie at Hapoel Tel Aviv in November 2002.[3]
