Powerful and strong, 'The Beat', as he is known down at the Dell, has made a big impact with his committed approach to the game.
A series of injuries meant he struggled to make an impact with the Saints, but that all changed in November 2000 when he began an unbelievable goalscoring run.
After going 18 months without a single goal, he managed to net ten goals in ten games by the end of the year, lifting Southampton into a good position ahead of the drop zone and well positioned to secure safety.
The England Under-21 international was subsequently linked with a call-up to the full squad.
Puts his new-found success down to garage music, and appeared in the video of the Artful Dodger's 'Woman Trouble' along with team-mate Matthew Oakley and West Ham's Steve Lomas!
However, his form dipped badly after that spurt, and he scored only two more goals after the turn of the year.
Beattie would then go 17 games without scoring towards the end of the 2000/01 season and the start of the next campaign. Signed a new four-year contract in March 2001.
He did find his form once again, but at one stage it looked like a he had sustained a serious injury when played against Manchester United in January. The striker fell heavily on his ankle and looked to be in excruciating pain.
By the look on the player's face you'd have though his career was under threat! In the end he missed just two months of the season.
By the end of the 2001/02 campaign he had netted an impressive 14 goals, taking his tally to 32 for Southampton in 133 games.
