Jermain Defoe came up with the goods again to provide Portsmouth with a 2-0 cushion for the second leg of their first adventure in the UEFA Cup but his missed penalty still leaves a nagging doubt about their trip to Portugal in two weeks.
Pompey, making their European bow after winning the FA Cup last season, pulled in a near full-house and created a carnival atmosphere at Fratton Park for the clash with Guimaraes despite the tea-time kick off.
"They (Guimaraes) showed enough to make us believe they are a dangerous side. This tie is not over yet. I don't know if two goals are enough," Redknapp said. "They were two good finishes and luckily Jermain is in sharp form and (Lassana) Diarra is just an amazing player - one of the best midfielders anywhere."
He added: "But their goalkeeper made some fantastic saves, including the penalty, and the one he stopped at the end from (Armand) Traore was amazing. If that had gone in it would probably have killed it.
"I'm happy enough though that we've given those great supporters a great night which they have deserved for so long. They've been through the barren years but now they are watching top Premier League and European football. Terrific for them."
