August 26, 2003 – the day Pompey climbed to the Premier League’s summit.
And a moment still imprinted on the memory of its architect.
Teddy Sheringham was the hero of the Blues’ 4-0 success over Bolton in the third match of the campaign.
Recruited from Spurs by Harry Redknapp to lead their maiden Premier League season, it was a magical display from the veteran striker.
Sheringham, aged 38, netted a 33-minute treble after Steve Stone had given the hosts the lead against Sam Allardyce’s side.
In the process, the ex-England international became the oldest player to register a Premier League hat-trick.
These days Sheringham is manager of Stevenage, who tonight visit Fratton Park.
And it brings with it a reunion with the club where he made 38 appearances and scored 10 goals during that 2003-04 campaign.
Sheringham said: ‘I would have been 38, it was against Bolton and I can still remember all the goals now.
‘I talked about it last year with Sam (Allardyce) with him then being in charge at West Ham. I brought it up a few times!
‘Still, this is a game against a team that will cause us problems, but it’s not a game we should be scared of and say “We don’t want to be going down there”.
‘We’re playing okay at the moment, but we could be better.
‘If we impose ourselves on Portsmouth there’s no reason why we can’t get a result, it’s as simple as that.
‘Fratton Park is a lovely place to go and play football and will probably be the largest crowd of the season that we will play in front of.
‘I’m sure it will be a cracking game, they play some outstanding football and we try to as well so let’s hope we come out on top.’
Back in the summer of 2003, having won the Division One title the previous season, Sheringham was recruited to add top-flight know-how.
Pompey kicked-off with a 2-1 Fratton win over Aston Villa, before drawing 1-1 at Manchester City.
Then it was the visit of Bolton on a Tuesday night – with the hosts topping the division at the end of it.
Sheringham’s hat-trick would be completed with a last-gasp penalty in the subsequent romp over Allardyce’s men.
It was part of a five-match unbeaten start to the campaign for Redknapp’s newcomers.
They finished the season in 13th position.
