Chris Sutton insists Celtic are "crying out" for a left-back due to Greg Taylor being out injured.

The Scotland international sustained a knock against Buckie Thistle which led to Alexandro Bernabei starting the recent victory over Ross County.

Celtic have been linked with a move for PSG's Layvin Kurzawa as a potential option in defence and Sutton feels the position should be a prioity for the Hoops.

Speaking to Sky Sports, he said: "I think Celtic supporters will be underwhelmed by the window so far based off Brendan Rodgers in the first half of the season calling for greater quality.

"They have brought Nicolas Kühn in who Brendan insists is better quality than they have and then there has been this call for another striker coming in which is always going to be difficult.

"As far as I can see Kyogo Furuhashi is always going to start but [Adam] Idah coming in on loan, it looks like, would be a good move after was on the fringes at Norwich City.

"I think the fact that they have not done a great deal of business, he will probably feel that the squad is a little short 

"I will be surprised if Celtic don’t bring in another left-back.

“They have been crying out for a left-back for a long, long time. I know Greg Taylor has done okay, but he is injured."

Meanwhile, Brendan Rodgers is reportedly "angry" at Celtic's lack of transfer business.

This is according to talkSPORT Alan Brazil who claims that that the Hoops boss is unhappy with how the January window has played out at Parkhead.

Celtic signed Nicolas Kühn from Rapid Vienna on a five-year deal earlier this month and have also look set to confirm the signing of Republic of Ireland international Adam Idah before the deadline.

However, Brazil feels the 50-year-old will feel like he has been left short in terms of options.

"I hope it is not true, but there are one or two rumours coming out of Parkhead, that Brendan is not happy about a couple of things.

"This only rumours by the way, but the pitch is not up to standard, I want more players, I need money for players and they are not given.

"So by all accounts he's very angry about it."
