Pundit Chris Sutton has taken to Twitter to react to Celtic's 5-0 home defeat at the hands of Paris Saint-Germain – and has told BT Sport that the result just sums up how much Celtic needed a new centre back.

The Bhoys saw off Linfield, Rosenborg and Astana to make it to the group stage of the Champions League once again, and were hoping for better fortunes than last season, when they were hammered by Barcelona in their opening group game.

However, the same thing happened again as Celtic were pitted against Paris Saint-Germain in their opening group game, with Brendan Rodgers' men losing 5-0 at Celtic Park.

Goals from the devastating trio of Neymar, Kylian Mbappe and Edinson Cavani all found the net in the first half, before Mikael Lustig scored an own goal and Cavani added his second to complete a 5-0 rout.

Celtic were destroyed by the French giants, and with another game against PSG as well as two against Bayern Munich and Anderlecht to come, Celtic may already be facing up to a battle to secure third place in their group.

Manager Brendan Rodgers will certainly be disappointed with the manner of Celtic's defeat, and pundit Chris Sutton has ripped into the 'embarrassing' defeat.

Sutton told BT Sport after Tuesday's game that Celtic were given a 'footballing lesson' by PSG, and he blamed large parts of the defeat on not signing a new centre half over the summer – but did praise young full back Anthony Ralston.

“They’ve been given an absolute footballing lesson.” said Sutton. “You can’t get away from the fact that was embarrassing from Celtic tonight. Brendan Rodgers spoke about being positive and getting close to them but they just didn’t in the first half. In every department, PSG were much better. You can say you’d expect that but I think Celtic could have done much better with the ball and without the ball.”

“They were scared, they were fearful and they were on the back foot. That wasn’t good enough. They gave PSG too much respect for me. Ralston stuck to his task but Celtic should have bought a centre half in the window and they didn't do that and that's why they were exposed,” he added.

Sutton also took to Twitter to share his thoughts on the game, tweeting that he would have been embarrassed if he was still in the Celtic side, again pointing out that the lack of a new central defender – despite receiving huge Champions League money – is what cost the Bhoys.
