Celtic suffered an embarrassing 7-1 defeat to PSG away from home in Paris in the Champions League last week.
The Glasgow giants actually look the lead, but then Unai Emery’s side made an astonishing comeback to pick up all three points with ease.
It was one of Celtic’s worst performances in Europe in recent years, although the Bhoys still have the chance to drop to the Europa League.
Former Celtic winger Provan has suggested in The Scottish Sun that manager Rodgers made the mistake of asking his players to play their normal game against PSG.
The 61-year-old former Scotland international winger has also questioned why Rodgers does not know his best two central defenders.
“The mistake Rodgers made was in asking his players to play their normal game against exceptional opposition,” Provan wrote in The Scottish Sun. “Celtic get time to play out from the back in Scotland.
“Scott Brown stars in our Premiership because he rarely has anyone in his face. Not in Paris where he struggled badly once again.”
“Dedryck Boyata and Jozo Simunovic were all over the place,” added Provan. "Getting tight when they should have been dropping, not matching runs, ball watching like schoolboys.
“It made you wonder how they spend their time at Lennoxtown. Brendan has had time to identify two defenders he can trust.
“But when the move for young South African centre back Rivaldo Coetzee fell through, there was no Plan B.”
Celtic won 2-0 against Motherwell at Hampden Park in Glasgow in the final of the Scottish League Cup at the weekend.
