Germany manager Joachim Low says his team will have to discuss their experience during the Paris terror attacks before returning to the city for Euro 2016 next summer.
Germany were playing France last month when the Stade de France was targeted as part of a series of coordinated attacks in the French capital that killed 130 people.
Two loud explosions were heard during the first half of France's 2-0 win over Germany and three people died outside the ground after suicide bombers tried to gain entry to the game.
The players were only informed after the match had finished and the German squad spent the night at the stadium rather than risk travelling back to their hotel.
Low's side were caught up in another terror-related incident just four days later when their friendly against the Netherlands in Hanover was called off shortly before kick-off due to fears of another attack.
The German coach returned to Paris for this month's Euro 2016 draw, which resulted in his team being put in a group with Poland, Ukraine and Northern Ireland.
Germany will play Poland and Northern Ireland in the French capital and Low said he planned to discuss November's incidents with the squad when they next meet for friendlies against England and Italy in March.
"These events in Paris and of course in Hanover too stayed with every one of us and probably will for quite a while, so I think we'll have to talk about it with the team again in March," he told German radio station Bayerischer Rundfunk.
"We're playing twice in the group stages in Paris so I think we'll have to prepare ourselves a bit and to adjust as a result."
He said such preparation was required so as "not to take these unpleasant memories into the tournament with us."
Low admitted that it had taken him two or three days to get back to normal life after what his team had gone through and that the German team's psychologist had been "a great support."
But he was reassured by his trip to Paris on Dec. 12 to discover who Germany's opponents at Euro 2016 would be.
"It was a return with mixed feelings and the memories also came back strongly," Low said.
"But I also experienced how extensive the security arrangements were and despite everything I had a good feeling at the draw because I already think that the French as hosts will do everything to ensure maximum security."
