Charlie Adam has cast doubt on Celtic's move for Albian Ajeti, warning that the new man may not cut it in Scotland.
The Swiss international completed a £5million move from West Ham United on Thursday, signing a four-year deal at Parkhead.
He'll provide Neil Lennon with another option up-front, but former Rangers midfielder Adam expressed some doubts about the signing.
Speaking on PLZ Soccer he said: "It's tougher coming to Scotland.
"Wait until you go to play Livingston, wait until you go to play Hamilton on the astroturf. That'll open the lad's eyes up.
"£5million is a lot of investment for Celtic, he's a young player.
"Have I seen enough of him? I've heard through the grapevine that he's not at the level that everybody thinks he is.
"Listen, Celtic are a great club. Peter (Lawwell) has obviously done a great job there in terms of how he fixes the finances.
"For that outlay they must like the lad, and like I say if he does well then he'll be worth £15-20million in the next 18 months.
"So it's a gamble, every transfer's a gamble, but Celtic seem to think it's a good buy for them.
"But where does that put Leigh Griffiths now?"
