England captain Rooney publicly apologised after pictures emerged of him at a wedding party at the team hotel in the early hours of the morning following the Three Lions’ 3-0 win over Scotland.
The Football Association has reminded the Manchester United skipper of his responsibilities and plan to review their policy of giving players free time on international duty amid allegations of drinking.
Klopp, however, told of a similar story of when he was in charge of Mainz and had a night on the town only for it to subsequently appear in a German newspaper.
“In our situation, I had a story with myself when we had 11 points and we were last in the Bundesliga table,” Klopp said.
“We had a Christmas break and friends of ours wanted to have a party in the city. Nobody saw me because I had a mask. I didn’t feel too good, but I needed a little bit of help and I went out.
“Then at the end there was one point when you are a little bit drunk, so I lifted the mask and then the next thing there is a picture. The mask? It was Santa Claus!
“The next day Bild said ‘That is how Klopp celebrates 18th place’. It is not actually like I celebrated but it was the picture. This happens and you go on.”
Behind closed doors Klopp is understood to take a pragmatic and common sense approach to the issue of Liverpool’s players drinking, but will not tolerate anything that puts results in jeopardy.
“We all know a few of them are doing it. Not going out but maybe having a party at home. They are young and sometimes if they don’t celebrate now it would be silly too,” Klopp said ahead of Liverpool's Premier League clash with Southampton.
“If they ask me six times a week ‘can we go out, can we go out?’. Seven times I will say no. They didn’t ask but if they did we would say no.
“I’ve no sympathy with it but when something happens, if it happens once fine him, take his money and do something good with it for the team, for the kitman or whoever.
“If then he thinks about the next drink, then think ‘really?’. I never had these problems actually but it can happen. It is not that serious. It doesn’t show anything that happens in general or with this player.”
Klopp was at pains to emphasise that it is wrong to demonise footballers for their off-the-pitch behaviour, when the incidents like the one involving Rooney were so commonplace in the past.
“Talk to the person, talk to the guy and convince him about the way to go. That is all. It is not really big. Make it as big as you want,” added the German.
“I feel for the players. We are all on the sunny side of life, earn a lot of money, do the job we love, but in the end there is a human being behind.
“Sometimes we are invited to something - a wedding, a birthday - we can still play the professional role and say 'no, we don't drink' and 'if you smoke, please, 20 yards between me and you'. That's not how life works.
“This generation is the most professional generation of footballers we've ever had. All the legends you still love, all the guys you still admire drank like devils and smoked like crazy and were still good players.”
