That was a season like no other as Harry Redknapp’s troops took the Blues to the Championship title and the then Premiership.
But Pompey had to wait for their moment of glory as the struggling Owls shocked the would-be champions with a surprise 2-1 win at Fratton Park.
Unsurprisingly, the fixture lives long in the memory of both sets of supporters.
But where are the Blues players who were named in Redknapp’s starting XI that day now?
We’ve had a look around to see...
5. Kevin Harper
The Scot made 113 appearances during his four-year stay at Pompey before moving to Stoke in 2005. His two-year spell at the Britannia Stadium was littered with loans, before a final move to Dunfermline saw him retire in 2009. The Scot keeps Pompey fond in his memory despite having many difficult times at PO4. Since retiring, the 45-year-old has trained for his UEFA A licence and has managed Albion Rovers up until 2020.

6. Nigel Quashie
The Scot sparked controversy by joining south-coast rivals Southampton when Harry Redknapp left tthe Blues in 2005. Quashie played 157 games during his five-year stay at Fratton Park before that move to St Mary’s - but following their relegation he later had spells at West Ham, Wolves, Birmingham and QPR. The 43-year-old retired in 2015 after a coaching spell in Iceland and has since set up his own coaching school called IPBA (Improving Players Development Academy).

7. Paul Merson
The much-loved captain who spent one season on the south coast was inducted into Pompey’s Hall of Fame in 2017. The 53-year-old had spells as a manager at Walsall following the end of his playing career. He is still a regular pundit on Soccer Saturday and recently released a telling story on BBC One about his long-term gambling addiction. Picture: Mike Hewitt/Getty Images Photo: Mike Hewitt
8. Tim Sherwood
The former Premier League winner joined Pompey in January 2003 and made 33 appearances during his 18-month stay at Fratton Park. After retiring in 2005, Sherwood became Harry Redknapp’s assistant at Tottenham, before moving to become Spurs' technical director. He was given the Spurs job in 2014 and also managed Aston Villa. The 52-year-old is now a regular pundit on Soccer Saturday and BT Sport. Picture: Jamie McDonald/Getty Images Photo: Jamie McDonald
