Germany and the Netherlands are set to face each other on June 13 in Kharkiv, and Mertesacker knows that club ties with his Dutch captain will not make the game any less easy.
"He said he would be happy to see me next summer - that was the first thing he said after the draw," Mertesacker told the club's official website.
"This is not a friendly though, it's a tough game and therefore both of us want to go through the group stage.
"It will be very tough to stop Robin. I think his best position is in the front, in the middle [as a striker]. There he can use his unbelievable skills. He is so reliable in scoring goals it is incredible."
The centre-back was undeterred by the fierce competition present in his group, which was labelled as the "group of death" in Euro 2012.
"It's a good group," he told the site. "Obviously it's one of the best at the Euros. I'm looking forward to playing those big teams and players like Robin."
Mertesacker is confident that the current German squad led by Joachim Low has the potential to go much further than their predecessors in the tournament, with the addition of new blood to the already experienced team.
"I think the last year with the 100 percent qualification means we have had consistency in our game," the 27-year-old mentioned. "That's the whole point of the new Germany and the way we play, especially in the last 10 qualification matches."
"Some players in my age group have more than 80 games and that is good experience. But we also have players who are 19, 20, 21 - that's an age to be in good shape and that's what we need next summer.
"We have had many chances in the last three big tournaments. We went to two semi-finals and one final and that's good for us but if you get that far it's better to get the title. I think that's the main point for the next tournament."
