Celtic manager Neil Lennon expects striker Lassad Nouioui to make a significant impact at the club this season.
The 27-year-old has been blighted by injuries since his arrival at Celtic Park at the end of August, but he has scored two goals in recent weeks in the victories at Aberdeen and over Hearts in midweek.
Lennon believes the Tunisia international has now reached full fitness and is confident he can progress on the pitch as well.
"We have been very impressed with Lassad, and he got 75 minutes on Wednesday, which is the longest he has played for us in any game since he arrived," the Celtic boss said.
"People wanted us to throw him in early, but we have to be careful with him. In two of the games we did play him, he had to come off injured, and we lost him for two to three weeks each time.
"That's not because of the physicality of the league here or anything like that, but because he did not have a pre-season.
"He was out of contract at Deportivo La Coruna and he did not get signed up with us until deadline day. The change in environment in football has probably caused all of that.
"He is a good finisher. I don't know how prolific he is going to be, but he has a nice touch and can link the play up very well."
