Haven't got a clue, Get off Twitter – Leeds fans rage as Radz gets latest message badly wrong
Andrea Radrizzani's not having a great time of things at the moment.
The season has ended with his club in 13th place and the fans not happy about the tour of Myanmar.
Now, he's managed to insult the fans again after getting the nickname of one of the club's legends wrong.
Radrizzani was responding to a message from the official Leeds United site, which sent out a happy birthday message to Jack Charlton.
Unfortunately, Radrizzani labelled Charlton as the "gentle giant", which was actually the nickname for John Charles.
Charles was the first British player to be signed by a foreign club when he joined Juventus in 1957 for a record fee of £65,000.
He joined Leeds when he was 17 years old and scored over 150 goals for the club, becoming a hero to many fans.
His nickname was "the gentle giant", a moniker that doesn't fit quite as well with the combative Charlton.
Plenty of Leeds fans were ready to point out Radrizzani's mistake, with one fan saying "you haven't got a clue have you?"
It's a good example of thinking before you tweet – here are the best reactions from angry Leeds fans:
