This could be good news for Celtic fans hoping Arsenal drop their interest in star left-back Kieran Tierney.
The Gunners have had a bid of £15 million for the player turned down, while there are conflicting reports regarding a second offer of £18 million that was also said to have been rebuffed by the Parkhead club.
A third bid had been expected but thus far there's been no further movement from Arsenal, who could be running out of available funds to successfully negotiate with Celtic.
It has been widely reported that manager Unai Emery has just £45 million to spent this summer, with £6 million already paid for Gabriel Martinelli.
If Saliba, as expected, completes his signing then it will take their spending over £30 million with other areas of the squad still to strengthen.
