Sebastien Bassong described the dressing room as 'sad and disappointed' after Sunday's FA Cup semi-final defeat against Pompey at Wembley - then set his sights on putting matters right against Arsenal on Wednesday.
It wasn't to be on Sunday. Chances came and went as it ended goalless in normal time and then Pompey took advantage of Michael Dawson slipping on the surface to take the lead nine minutes into extra time.
We hit the post and had a goal disallowed before Kevin-Prince Boateng wrapped up Pompey's 2-0 win from the penalty spot in the final minute.
"We are all very down because we expected a lot from the FA Cup," said Sebastien.
"We had a couple of chances which we missed and then we conceded a goal, which was unlucky.
"I feel really sorry for Daws because I think it was the first time in the game that he slipped. He played really well and the goal wasn't his fault, it was just bad luck."
Sebastien knows the players must pick themselves up quickly as we resume the chase for fourth place in the Barclays Premier League - starting with the big one against Arsenal at the Lane on Wednesday night.
The weekend's league results saw Liverpool slip up at home to Fulham but Manchester City won again to stretch their lead in fourth to four points, having played a game more.
"We are still in the race for fourth spot and this will be a big game against Arsenal which we need to win," stated Sebastien.
"Obviously this game is coming straight after the defeat to Portsmouth which means we can get that result out of our minds very quickly.
"We know it will be difficult but we have been strong at home this season and must believe that we can get a result."
