Former Rangers kid Wilson is on Celtic's shortlist
Celtic manager Ronny Deila will try to persuade Jason Denayer and Manchester City to extend the centre-back's loan deal next season - but Hearts captain Danny Wilson is also among his defensive targets.
Denayer made his full international debut in Belgium's 1-0 European Championship qualifying victory in Israel on Tuesday night, coming on as a 67th minute substitute after Vincent Kompany was sent off for two bookable offences by Premier League referee Mark Clattenburg
The 19-year-old also faces competition from Kompany at City, and Deila would welcome another season-long loan arrangement.
But, with Denayer due to spend pre-season with his parent club in a bid to prove himself, there is no guarantee he will return and certainly not in time for Celtic's Champions League qualifying campaign beginning in mid-July.
So Deila confirmed he would look to sign a centre-back and responded to reports that former Rangers player Wilson was among his list of potential targets.
"That is one of many names we are talking about but there is nothing serious in that," Deila said. "But he's a good player."
Deila, who spent last week watching Norway training before their 5-1 defeat in Croatia, added: "Jason is going back to Manchester City after the season to have a pre-season and we will see if we can get him back or not. That is something we want, but we have to co-operate with City.
"But I think it's good for him to stay here because hopefully we will get Champions League qualification and that will make him even more experienced.
"Jason is ambitious - he wants to play at the highest level he can. But it's playing that is the most important thing, and playing at Manchester City is very, very hard. If not, I think Celtic is a good club for him."
Celtic were involved in another loan deal this week when 18-year-old midfielder Liam Henderson joined Rosenborg until the summer.
Henderson has made 22 first-team appearances, but competition has increased recently with the signings of Stuart Armstrong and Gary Mackay-Steven.
"Rosenborg called me and asked if we had a midfielder that could be available and Liam Henderson is a very, very talented player and he needs games," Deila said.
