Chris Sutton has accused Celtic of a dereliction of duty in their failure to recruit any centre-halves during the summer, and criticised Jozo Simunovic and Dedryck Boyata after Celtic’s 7-1 hammering against PSG.

Celtic’s backline has been badly exposed in the Champions League this season, with 12 goals conceded in two games against PSG.

Writing in his column in the Daily Record, Sutton claims that Celtic will never make real progress in Europe unless signings are made.

He said: “If there’s any criticism of Rodgers it’s that if you don’t recruit then you will just stand still and he’s killing himself by being too loyal to players who have been found out at elite level.

“Of course if you sign better central defenders then you’ll have a better chance of competing against the top sides.

“I understand the financial gulf but it’s too easy to use that as an excuse for the 7-1 defeat in the Parc des Princes.

“And it’s a load of rubbish saying that signing a centre half or two wouldn’t have made any difference against the quality of PSG.”

Sutton singled out two Celtic centre-backs for criticism, saying, “You have to bring in better quality and the facts are Jozo Simunovic is promising but heavily injury prone and can’t be relied upon.

“Dedryck Boyata always seems to have a mistake in him at that level.”

Despite Sutton’s remarks, Celtic still seem likely to clinch Europa League football after Christmas,
