Neil Lennon wants new players in his Celtic squad this summer.
The Hoops boss has already lost Victor Wanyama to Southampton for more than £12million and could quite possible see star striker Gary Hooper leave for QPR or Norwich City.
After easing past Cliftonville 3-0 in the first leg of their Champions League second round qualifier on Wednesday, Lennon admitted he needed some new signings ahead of another busy campaign.
"Hopefully we've negotiated the tie but we need new bodies in for the next round and we're going to do that," he said.
"We're actively looking at strengthening the squad as there's money available from the Wanyama transfer.
"I'd like someone in before the second leg next week if I can so we can bed them in as quickly as possible. If we could get one in early next week, I'd be delighted but at the moment we aren't close to anything."
