The window has been extended by 24 hours to close on September 1 and it seems highly unlikely the Pompey boss will put his feet up in a quest to bring in a fresh recruit.
Having already secured Armand Traore on loan from Arsenal, Redknapp is looking for at least another player to borrow to top up his squad ahead of the European adventure.
But unlike previous deadline days when he has been particularly busy, Redknapp insisted there would be no big transfers being rushed through to beat the midnight deadline.
He said: 'We're looking at only loans, really. If I could find someone really good I would get him, but other than that, we're okay.
'We've got a good squad and we've got people coming back fit.'
Traore made a promising debut on the left of midfield last night, despite missing a chunk of Arsenal's pre-season through injury.

Redknapp said: 'Traore can play anywhere down that left-hand side. He did well and I like him. He's quick and he's got a big future.
'I took a chance and played Sylvain at left-back, but he's played there for a fair part of his career.
'It was a balancing act. I thought I'd sit him in there behind the young kid and let Traore play in front of him.'
Pompey have yet to register a point in their two Premier League games so far and have also yet to score in three matches, including the Community Shield.
But Redknapp insisted the quality of opposition was the major factor behind that statistic.
He said: 'We haven't scored in three games, but we've played Manchester United twice and Chelsea, so that's a consolation. We've got another hard game at Everton this weekend.
'Out of those three games last season, we took one point.
'We might take none this year, we might take one and we might take three, but they are difficult games.'
