Speaking to CardPlayer.com, the former Germany international said: "Cristiano Ronaldo’s influence was very limited at the last Euros and I think you have to keep in mind at this World Cup, he is another year older.
"He still scores goals but they have good forwards like Goncalo Ramos who can’t get a game, I think it’s time for someone else to have a chance to shine in the team. If we see him at the World Cup, I’d be very surprised if he had a big impact."
