Liverpool boss Klopp is set to be linked with the Germany job in the wake of their shambolic World Cup campaign.
Low penned a contract extension shortly before the competition started but, after winning just one game from three, now faces an uncertain future.
Arsene Wenger has been made the early favourite to take the Germany job but Klopp, who has steered Liverpool to three cup finals in as many years, is set to be on their radar as well.
And Liverpool fans have taken to Twitter to express their worries that Klopp may be in line to take over.
@SovietShooter said: “The pessimist in me is really hoping that Germany doesn’t fire Löw… as I see the clear #1 choice for his replacement as Klopp.”
@Eduard_hero added: “We should go ahead and upgrade Mr klopp’s contract… Germany might be looking to get a new manager.”
@Luna_Kevin5 chipped in with: “I feel like Germany going to try hard to get Klopp /:.”
“I’ve just got three words for #Germany – HANDS OFF #KLOPP!” were the words of @markicam.
@TWGerken then said: “My biggest concern right now is that Loew will go tonight and Germany might offer Klopp the national team job…”
Klopp has talked up managing Germany before.
Speaking in 2014, the Liverpool boss said: “Not yet, but obviously it’s basically a very attractive proposition.
“If they were enthusiastic about me taking on the national team at some point I’d obviously think it over, although quite a lot of things would have to come together for that to happen.
“But joking aside we have a fantastic national coach.”
