The one-time Fratton favourite admitted it was an ‘incredible’ day, despite being on the losing end against Chelsea in 2010.
The then Spurs loanee started the 1-0 defeat to Carlo Ancelotti’s side, which was played in front of a capacity 88,335 crowd at Wembley.
Kevin Prince-Boateng had the chance to hand Avram Grant’s Championship-destined outfit a shock lead – but his penalty was saved by Petr Cech, before Didier Drogba scored the decisive winner five minutes later.
It was a game that marked O’Hara’s last outing for the Fratton Park side, with his loan from White Hart Lane coming to a conclusion.
During his season-long spell on the south coast, the midfielder made 29 appearances, while scoring on three occasions in all competitions.
O’Hara played a key role in Pompey’s run to the final, netting against Southampton in the fourth round, yet was sidelined for the historic 2-0 victory against Spurs in the semi-final.
Despite the club suffering a torrid season and problems off the pitch, finishing bottom of the Premier League, the ex-England under-21 international was awarded the Blues’ player of the season and has always been open to a Fratton Park return.
Ahead of today’s FA Cup final between Chelsea and Liverpool, the former Pompey ace was again reflected on his time at PO4, admitting it was a special to feature for the club in the final that day.
O’Hara tweeted: ‘I’m at Wembley today for the FA Cup Final.
‘Always remember getting there with Pompey and that day was just incredible for me.
‘It still has the attraction as the most historic trophy in the world.’
