Celtic have only signed three players so far this summer.
Neil Lennon might've just hinted that Celtic could sign a new player before Wednesday's Champions League visit of Nomme Kalju.
The Hoops have had a relatively quiet transfer window in comparison to those on the other side of the Old Firm divide, signing only three players.
But Celtic have still spent £10 million nonetheless, with Christopher Jullien representing a sizeable addition for £7 million, while Boli Bolingoli cost £3 million.
Jullien, who signed from Toulouse in Ligue 1, hasn't yet made his competitive debut after being benched for the first-round Champions League qualifier against Sarajevo.
And Lennon has said that the chances of him facing the Estonian side next week could hinge on whether he brings in another body.
He told The Scottish Sun about Jullien: "Whether we start him against Kalju on Wednesday is something we will have to gauge as we go along. It will also depend on whether we get someone else in.”
Reading between the lines, Lennon, who also nabbed 18-year-old midfielder Luca Connell, isn't ruling out the possibility of signing his fourth player before the Tallin-based club come to visit.
If there is a new signing, it looks plausible that it could be Hatem Abd Elhamed who, according to BBC Sport, Celtic have agreed a deal with Hapoel Be'er Sheva for.
