Celtic hero Peter Grant says there is a key question mark surrounding his old club's move for Kelechi Iheanacho.
The striker signed for the Scottish Premiership champions the day after the transfer window slammed shut.
Iheanacho penned a one-year deal at Parkhead, with Celtic holding the option to extend it by another 12 months.
Speaking on Go Radio, Grant outlined the sole concern he has surrounding the move: "The only question mark we have just now is because we haven't seen him play recently," he said. "At 28, his peak years should be there, but we don't know where he is because we haven't seen him play.

"I can tell you this - if he is fit, there is absolutely no doubt he is a talented boy. There is no doubt.
"He could end up the saviour in the respect of bringing the peace between everybody. That is what you are looking for and the pressure that comes with him.
"The boy won't get time to break himself in. He will get judged in 10 minutes, and that is the way football is in Glasgow.
"But if he is at his peak and fit to play, he is a talented boy."
Iheanacho could make his Celtic debut a week on Sunday against Kilmarnock at Rugby Park.
He was named in their 24-man UEFA Europa League squad ahead of fellow strikers Callum Osmand and Shin Yamada, who were signed earlier this summer.
