It turns out that it's not just Arsenal fans who have a problem with Mesut Özil's laissez faire work rate, as the man himself reveals a pretty intense bust-up he once had with Jose Mourinho while the two were at Real Madrid.
With the Arsenal playmaker (at least when he feels like it) set to release his autobiography later this year, German newspaper Bild has been serialising extracts from the book ahead of its publication.
In an extraordinary section that reads ever so slightly like an erotic romance novel (not that we'd know of course), Ozil recounts a furious dressing room argument with Mourinho.
"You think two beautiful passes are enough, he said. You think you're so good that 50% is enough.
"He pauses. Stares at me with his dark brown eyes. I stare back. Like two boxers at the stare-down before the first round.
"He shows no emotion. Just waits for a response from me. How much I hate him right now. And I love Mourinho actually."
"Oh, are you giving up now? You're such a coward. What do you want? To creep under the beautiful, warm shower? Shampoo your hair? To be alone?"
"Or do you want to prove to your fellow players, the fans out there, and me, what you can do?"
Ozil also revealed the details of his departure from Madrid, after his father (and then agent) fell out with Real Madrid head honcho Fiorentino Perez during contract negotiations.
"I had fallen into disgrace with the boss [Perez] of my club, although I had not done anything wrong at all," claimed Ozil.
"I was threatened with sitting in the stands. Suddenly I had to act. For my career. It was not at all questionable to play any more - especially if this decision were not based on performance criteria
"But there was also this man with the quiet voice and the wise words that showed me that he really wanted me to be on his team, Mr Wenger."
And the rest, as you know, is sort-of-disappointing-with-flashes-of-brilliance history.
