Portsmouth manager Michael Appleton wants three new signings before the weekend after watching his side salvage a 2-2 draw at Colchester.
Substitute Jordan Obita scored with his first touch on his debut as Pompey claimed a dramatic point in an entertaining clash at the Weston Homes Community Stadium.
Appleton said: "We need an absolute minimum of three players to be competitive. If I can bring all three of them in before the weekend, that would be fantastic.
"I'll be working hard to convince people that we need to get these players in before Saturday."
He added: "I'm not sure how we've not managed to get three points. From a positive point of view, apart from the two goals we conceded, it couldn't have gone much better. We've been working hard and you have to try and get the right players in."
Portsmouth went ahead on the half-hour mark when Luke Rodgers slotted past goalkeeper Mark Cousins from Liam Walker's threaded pass.
Colchester equalised in first-half stoppage-time through left-back Michael Rose's magnificent first-time 30-yard strike. In the second half, Magnus Okuonghae slotted in from close range with six minutes to go but Obita tapped into an empty net after Rodgers had struck the post, to secure a well-deserved point.
Colchester manager John Ward said: "It was a terrific game of football and a terrific advert for our division. I had no surprises at the way Portsmouth played.
"They have a good organisation out there and two centre-halves who have played in the Championship. We knew that we would have a tough game on our hands and so it proved, but I think they knew that, too.
"We were disappointed because we were leading with only a couple of minutes to go. But you couldn't really deny Portsmouth the point, because it was that sort of game of football."
