Smith returned to England and Arsenal in the fall of 2004.
She officially rejoined in 2005 after being treated at the Sporting Chance clinic.
However, she was yet again hampered by injury, this time by a stress fracture in her foot.
She returned to action at the end of the 2004–05 season, scoring a goal from 30 metres out against Charlton Athletic L.F.C. which clinched the Premier League title for Arsenal.

In Arsenal's "Quadruple" winning season of 2006–07, Smith scored 30 goals in 34 games across the four competitions.
However, she missed both legs of the 2006–07 UEFA Women's Cup final through suspension, after being sent off for giving the finger to opposition fans in the semi-final.

During Smith's Arsenal career since rejoining in 2005, she appeared in 66 Premier League games scoring 73 goals, 16 FA Cup games scoring 13 goals, 10 League Cup games scoring four goals, 18 UEFA Women's Cup games scoring nine goals, and two Community Shield games scoring one goal for a total of 112 appearances and 100 goals.
In her last competitive game for Arsenal, Smith scored a hat-trick to help Arsenal to a 5–0 win over Doncaster Belles in the FA Women's Premier League Cup final.
She won the FA Women's Players' Player of the year in 2006 and 2007.
