Grosskreutz in shock over Klopp's decision to take Red Bull job

When it was announced earlier this week that Jürgen Klopp is Red Bull's new Global Head of Soccer, it came as a shock to many, including former Borussia Dortmund player Kevin Grosskreutz.

Critics believe Klopp has tarnished his reputation by taking a job with Red Bull, who are generally very unpopular with German football fans due to the commercial setup they've implemented at RB Leipzig.

And speaking on his podcast ‘Viertelstunde Fußball’, Grosskreutz made it very clear how he feels about Klopp's decision, which left him in a state of shock.

"I woke up, I had 30 messages on my phone and I thought: What happened? I thought I was dreaming, then I hoped it was fake news. Two hours later it was official. It was pretty shocking and sad. Somehow it hasn't really sunk in yet," said Grosskreutz, who made 176 Bundesliga appearances for Borussia Dortmund under Klopp.

"I don't think anyone was expecting it. It's very, very strange and I can't really comprehend it yet. It's like shock! Nevertheless, he's a friend of mine and I owe him a lot. And I will always be grateful to him.

“As a football fan, I think it sucks, to put it bluntly! But as a friend, you have to accept decisions being made. When we meet, I'll still tell him personally that I think it's shit that he does something like that!”
