Tottenham coach Juande Ramos was full of praise for his goalkeeper Paul Robinson.
'He did a great job, he did everything he had to do,' said the Spaniard. 'We want him to produce the best performance possible and give the best of himself. He was out for a while but his performance was magnificent.'
The Spurs head coach also could not guarantee a Wembley place for Robinson.
'We have three days to recover,' he added. 'We can have a close look at the line-ups, how they recover. There is a lot of things to consider before deciding on the final team line-up.
'It's important that all the players are fit enough and in the right condition.'
'We were disappointed in the second half. We sat back and should have got two or three - but we are glad to have gone through,' O'Hara said.
Pascal Chimbonda was substituted after picking up what appeared to be a knee injury but he should be fit to face Chelsea.
'It doesn't seem like a particularly serious injury and he should recover in the three days before the final,' Ramos said. 'But the most important time is the first 24 hours and we will check on him and see how he is.'
Paul Robinson is targeting a place in goal at Wembley after earning a recall for Tottenham UEFA Cup victory over Slavia Prague.
It put him in the frame for the Carling Cup final against Chelsea on Sunday.
'I'd like to think so,' he said on ITV4. 'I hope so.'
Robinson saved in the first half from Jaroslav Cerny's swerving shot, then in the second half he was tested by David Strihavka and Milan Ivana as Spurs nervously closed out victory.
'I've just got to answer to myself,' he added. 'I know how I've been playing, or not playing as the case has been.
'I just wanted to get back in the team and back on track.
'I'm delighted to be back in the team, in a team that's playing well.'
Slavia boss Karel Jarolim felt conceding an early goal immediately put his side on the back foot.
'We didn't start well. When they took the lead nobody was doubting that they would go through,' Jarolim said. 'After the equaliser we put them under pressure and created promising chances.
'We saw an aggressive, compact team and the only thing that was missing was a goal to send it into extra-time.'
