Frank McAvennie is expecting Celtic to sign two or three more defenders before the window slams shut, Football Insider report.

The Lowdown: Starfelt deal

Celtic have made three big-money signings following Ange Postecoglou’s arrival in Liel Abada, Kyogo Furuhashi and Carl Starfelt.

Starfelt, who was unveiled as the club’s new number four last week, cost Celtic £4.5m from Rubin Kazan.

All three featured for the club in the 2-1 opening weekend defeat to Hearts, and McAvennie wants more defenders to follow Starfelt through the Parkhead door.

The Latest: McAvennie’s comments

McAvennie was talking to Football Insider on the Hoops’ backline after Starfelt linked up with Celtic following his move last week.

He admitted he was ‘fed up’ with guessing on what Celtic’s board will do next in the window and labelled the club’s options in defence as ‘embarrassing’ following Kristoffer Ajer’s move to Brentford.

“They need so much more.

“They have let Kristoffer Ajer go and everyone else is nowhere near good enough. It’s embarrassing.

“The boy Starfelt has come in, is he going to be enough? I don’t know anything about him.

“We’re hoping he’s a good player and he can do it but he needs help.

“We can’t just sign him and go see that as the defence being sorted. The rest are too weak.

“He can’t do it all on his own. The warning signs were there when Michail Antonio tore them apart.

“Honestly we need another two or three defenders in before the window shuts.

“Whether the board will sanction that, who knows? I’m fed up of guessing.”

The Verdict: He’s spot on

McAvennie is spot on with what he is saying. Postecoglou had to use youngsters Stephen Welsh and Dane Murray at centre-back in their Champions League qualifier before throwing in Starfelt against Hearts, while also having just Anthony Ralston and Lee O’Connor as right-back options.

Greg Taylor has been used at left-back in all three of Postecoglou’s competitive games in charge, with Boli Bolignoli not in the squad on the weekend.

Another quality centre-back and two full-backs could prove handy to bolster the club's options going forward, and McAvennie’s frustrations may well be shared by a lot of Celtic supporters.
