Speaking on his podcast Simply Luppen, Kroos, who retired last summer, said he was stunned when he heard about the change.
“I almost fell off my chair. Kwasniok has already said it. I didn't even know it was being introduced now. There are so many problems – including with VAR," Kroos said on his podcast.
"[The action is] nice and well-intentioned, but when you put yourself in the situation, I think to myself: 'Yeah, great.' You shake hands 70 minutes beforehand and say: 'Respectful interaction,' etc., but you don't yet have the emotions you have in the game.
"This has absolutely no effect and no value, especially since it disrupts the captains' preparations for the match. You're right in the middle of preparation. Now let's say how much we love each other. And in the fifth minute, there's no more handshake, then you get a yellow card."
