Celtic have been left to pore over the wreckage of another bruising Champions League defeat.

The 6-0 mauling in the Metropolitano at the hands of Atletico Madrid was a sobering experience for Celtic boss Brendan Rodgers and his players.

Braces from Atletico stars Antoine Griezmann and Alvaro Morata as well as strikes from Samuel Lino and Saul Niguez, saw Diego Simeone's side run out comfortable winners at the Civitas Metropolitan Stadium.

A red card early in the first half for Daizen Maeda changed the course of the game for the Scottish champions but the same old problems resurfaced and plagued Celtic on the Champions League stage once again.

The Northern Irishman bemoaned the fact that VAR and the home crowds reaction contributed to Serbian referee Ivan Kruzliak dismissing the Japanese winger.

The 50-year-old said: " I don't want to go on about officials as I've never been one to complain as you have to accept decisions.

"It feels like a computer game as everybody is constantly looking at the screens. When the referee comes over to see the incident it is not a reflection of the actual challenge.

"It is a still with his foot up and straight away plants the seed for the referee. From there, his influence is to send the player off."

The inquest has no doubt begun already but where does the blame lie for the men in green and white's latest capitulation in Europe?

Did the Celtic board arm Rodgers sufficiently enough with quality players in the summer transfer window to be fiercely competitive in this season's competition?

Why did the Celtic hierarchy make a big song and dance about their surplus of cash reserves and not hand their manager a warchest in the summer?

Will they now back Rodgers sufficiently in the January transfer window?

Has the time finally come for the club to stop signing project players?
