Frank McAvennie tipped Celtic to sign a left-back to provide competition or even replace Greg Taylor after an opening offer for Alfie Doughty was rejected by Charlton Athletic.

The Parkhead legend, speaking exclusively to Football Insider correspondent Dylan Childs, believes that Hoops boss Neil Lennon has identified Doughty as a potential solution to the left-hand side of the defence.

The 20-year-old is highly versatile and can play as a central midfielder, a left-sided midfielder or as a left-back.

Doughty, who has entered the final 12 months of his contract at Charlton, is understood to have been watched by Neil Lennon’s scouts in preseason.

Addicks boss Lee Bowyer revealed earlier this week that the League One club had rejected an offer from the Scottish Champions for the London-born player.

When asked by Football Insider if Doughty would be a welcome addition at Paradise, McAvennie said: “They want him in for Greg Taylor.

“Neil Lennon sees Doughty as an option at left-back.

“They have not met the asking price for him but they need someone to push Taylor or even take his place. Let them two fight it out.

“It is an important season this year and with Bolingoli out of the loop, and I do not think he will come back in, they need to sign another.”

When speaking on Doughty’s future, Bowyer said: “We did turn down an offer from Celtic and they were at the game at the weekend, from what I understand.”

The bid casts further doubt over Boli Bolingoli’s future in Glasgow with AS Roma reported to be considering a move for the frozen-out defender.
