Former Republic of Ireland international Andy Townsend has urged Celtic's Adam Idah to raise his game - or face being replaced.
The striker, who has scored 14 goals in 45 appearances since his switch from Norwich City, has mostly been on the bench this season.
Despite his potential, the 30-time Republic of Ireland international has not been able to secure a starting spot under manager Brendan Rodgers.
Townsend, a former Norwich midfielder, said: "Celtic spent on Adam Idah last summer, but it wouldn't surprise me if they go and buy another striker this summer—and I think they will.

"Now, he's an experienced boy.
"He's been around long enough, and I think he's got to hurry up and find that extra 10, 15 per cent, which is required to nail a position down somewhere consistently where he is absolutely the number one, whether it's club or country, he's not really been able to do that.
"If he's not careful, someone else will come in at Celtic because Brendan Rodgers is not going to wait.
"Celtic never wait and they’ve lost Kyogo Furuhashi, but they do have Daizen Maeda who poses more of a threat down the middle.
"Adam has got to take the opportunities that he's being given."
Idah joined Celtic initially on a loan deal until the end of the season from Norwich, where he made a big impact.
Scoring nine goals in 19 appearances, the striker scored big goals against the likes of Hibernian, Motherwell, and especially Rangers, where he scored the winner in the Scottish Cup final last May at Hampden.
He signed a five-year deal with the club back in August.
Townsend added: "That's been Adam's problem.
"Wherever he has been, you are looking at him and thinking that there is probably more in there to give and I don't think it's always coaches that can do it.
"I don't think it's always managers who can find that.
"It has to come within how much you really want it.
"He needs that edge, Adam.
"I don't think it's quite there yet.
"He needs a big summer.
"He needs a strong summer.
"He needs to look after himself physically and be in great condition when he returns, but mentally find another dimension to add something to his game."
With his talent evident, Idah must now heed Townsend's advice if he is to impress Rodgers and cement his place in the starting line-up for both Celtic and Ireland.
