Indeed, the former Liverpool defender claims he had to contend with a manager who wouldn't even let his players look at their families in the stands during a cup final!
Yes, after criticising Krul for his pat on the back of Jermain Defoe during the Wear-Tyne derby last Sunday, Carragher has revealed that ex-Liverpool boss Gerard Houllier was even against players waving to their family ahead of the 2001 FA Cup final.
Carragher, though, says he 'loved' that about his manager - explaining that it was this kind of experience that helped form his strong feelings about 'sportsmanship.'
After the game is fine, argues the former Liverpool defender. But never during.
He said: "Houllier even told us before the FA Cup final in 2001 that he didn’t want us looking into the stand to see our families; given that I grew up watching players make the long walk at Wembley while waving to the crowd, that was quite a statement.
"But do you know something? I loved that. There is a time and a place for showing mutual respect and it is after the final whistle has gone and you are in the bar afterwards."
Interestingly, Liverpool face Krul and Newcastle next on Monday night, with the Reds in need of a win to get their Premier League campaign back on track against a Magpies side in absolutely woeful form.
Whoever comes out on top at Anfield, perhaps they'll share a relieved look with their relatives at the ground - now that Houllier isn't their manager!
