After hitting 59 goals in 155 games for Bristol Rovers, Lambert joined Southampton in Aug. 2009 in a transfer worth over £1 million to his former club.
The Saints had been relegated from the Championship in the previous season, and the striker was viewed as the man to spearhead an immediate return by then-manager Alan Pardew.
Lambert finished the season as the club's top scorer, but Southampton finished outside of the play-off positions.
However, the striker won his first piece of silverware after scoring a penalty to help the Saints beat Carlisle United in the Johnstone's Paint Trophy final at Wembley.
In Sept. 2010, Nigel Adkins was appointed to succeed Pardew, who had been sacked in the previous month, and the club and Lambert were set on an upward trajectory.
The Saints clinched promotion back to the Championship with the help of 21 goals in 50 games in all competitions from the striker.
Even better was to follow in the 2011-12 season, as Adkins guided the Saints back into the top flight. Lambert picked up the Championship Player of the Year award, as BBC Sport reported.
He finished the season with 31 goals in all competitions, with 25 of those coming in the league.
