Celtic are set to land Teemu Pukki from German club Schalke this week.
The Hoops are working to secure the 23-year old Finnish striker on a £3million deal once Schalke complete their Champions League playoff qualifying duties against PAOK in Thessaloniki on Tuesday night.
It is believed that Celtic and Schalke are still trying to agree on the actual fee for Pukki but agent Tapio Raatikainen and German-based partner Gerrit Gertung believe a deal can be done.
"There are concrete pre-arranged conditions that have to be met. Then, to my knowledge, Pukki can leave,£" said Gertung.
