Sunderland boss David Moyes could not resist a barbed comment in Jurgen Klopp's direction after his side fought back twice to earn a 2-2 draw with Liverpool on Monday.
Klopp had criticised Sunderland's defensive approach in the reverse fixture at Anfield in November, but Moyes no one would be complaining if a foreign coach used the same tactics.
"Maybe if I was a German manager, you might praise that, actually," he said after the game. "If I had been German, you might have been saying, 'Great, you're doing something different.'"
Klopp also complained about the free kick awarded by referee Anthony Taylor which led to the second six minutes from time.
