Ex-Rangers star Charlie Adam has suggested that Celtic new Bhoy Albian Ajeti 'is not at the level everyone thinks'.

The former Light Blues midfielder made the claims on PLZ Soccer that Ajeti could potentially find it tough in the Scottish Premiership after making a £5million move from West Ham down south.

Ajeti wasn't given a crack at the whip in the English Premier League after signing under Manuel Pellegrini. When David Moyes then got the Hammers job, Ajeti slipped further down the pecking order. However he showed enough for Celtic to splash the cash. Adam - who has played in both leagues - believes Scottish football is harder to adapt to and reckons Ajeti could struggle to do so on astroturf.

But while he reckons the transfer is a gamble, he admits that, if it pays off, Neil Lennon and his club could be looking at a star player and a significant fee to sell him on again down the line. "If you think the level of the English league is high, it's tougher coming to Scotland," Adam said.

"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. So it will be a surprise.

"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?"
