He spoke of the English players who could pose danger to Joachim Low's side, and one of them is the Man United captain.
"You have Harry Maguire, who kind of frightens everybody when this guy rolls through midfield," Klinsmann said.
"He reminds me a bit of Lucio, the Brazilian centre-back — he looks like a Mustang running through everybody."
In 2002, he also played every minute of Brazil's World Cup title run, being just one of three players to do it. Such resilience is clearly something that Maguire can associate himself with - he's likely to start against Germany on Tuesday, even though he was in major doubt for Euro 2020 at all due to a nasty ankle injury.
