Alex Bruce has claimed Marcelo Bielsa has no choice but to adapt his methods at Leeds United to the remorseless nature of the Championship.

Speaking exclusively to Football Insider, the ex-United defender, 35, insisted the English second tier is physically more demanding than the Premier League.

Bruce pointed out that Bielsa’s strict adherence to his principles of intense training and repetition, which is then replicated in matches, has to be tweaked over the course of a 46-match campaign.

Asked by Football Insider if Bielsa is too stuck in his way, the son of Newcastle United boss Steve Bruce replied: “When you think of the leagues that he’s been in and managed in, there’s only one Championship. Physical-wise, you play Saturday, Tuesday, Saturday, Tuesday – it’s relentless, speaking from experience.

“It’s probably the toughest league possible, I found the Championship physically harder than the Premier League because you play two games a week all year.

“You don’t get any mid-season breaks or anything like that.

“Whether he hasn’t adapted to it, I’m not sure, I’ve never worked with him so I wouldn’t know.

“However, if you do go into it and you’re not keen to change your ways or change your methods to suit how the Championship is, nine times out of ten you’ll get found out.”
