Thomas Frank, Oliver Glasner & Arne Slot – factors that lead to managerial pressure

Falling out with owners or other people in a club’s hierarchy is always a problem too.

That played its part in Amorim’s departure after the Portuguese criticised Manchester’s United board in an explosive news conference after a 1-1 draw with Leeds.

He challenged club chiefs to let him do his job without interference, with earlier comments about the Red Devils’ transfer strategy having hinted at possible friction behind the scenes.

The day after the Leeds match Amorim was sacked.

Maresca was dismissed after a poor run of results left Chelsea‘s top-four hopes in the balance – but he also paid the price for a disagreement with the hierarchy.

Nuno, meanwhile, led Forest into Europe last season but then fell out with owner Evangelos Marinakis over transfer dealings – and was axed.

Brendan Rodgers officially resigned as Celtic manager earlier this season – after a catastrophic breakdown in his relationship with the board.

And this weekend Glasner rounded on Palace’s owners, saying he felt he and his players had been “abandoned completely” in a criticism of the Eagles’ transfer strategy.

Glasner confirmed on Friday he will leave Palace when his contract expires at the end of the season – but whether his outburst accelerates his departure remains to be seen.

“I don’t think there is a chance he can be there next weekend,” Rooney said.

“Once you speak against the owners there is only one result.”
