Celtic have agreed a deal worth up to £9.5m for Norwich City striker Adam Idah.
It is believed the initial fee will be £8.5m, with add-ons worth £1m, as Idah is keen to return to Celtic and is prepared to agree the terms of a long-term contract.
Norwich also included a 15% sell-back clause in the deal.
The Scottish Premiership champions had an initial offer of £4m rejected in July, but a new and improved offer, believed to be in excess of £6m plus additional costs, led to talks between the clubs resuming last week.
