Ange Postecoglou has been told he "dropped down in club size" by moving to Tottenham from Celtic.

Robbie Savage reckons the Australian made a great step in his career by joining Spurs.

However, the ex-Manchester United kid believes he ultimately downgraded in the size of the club he was operating at.

The former Wales international told Star Sports’ Route One Football: “I think [joining Tottenham] is a brilliant step for Ange Postecoglou – even though he’s dropped down in club size. He was brilliant with what he did at Celtic, particularly with the brand of football – I keep a close eye on the Scottish Premiership, and you have to win the league if you’re Celtic or Rangers, which he did convincingly by winning the treble.

“But Spurs haven’t got that star [for winning the European Cup] on their shirt like Celtic do, nor do they have Champions League football like Celtic, so is it a gamble for him? He needs time at that football club, it’s as simple as that – look what happened with Jose Mourinho.

“The club are going with proven winners in recent years, and Postecoglou was winning at Celtic, so will he regret it? He was adored there, had Champions League football, and would probably go and win the Scottish Premier League again, so I think he’s taken a step down.”

Meanwhile, Savage went on to suggest that Wolves boss Julen Lopetegui could leave his post shortly after the season commences

When asked which manager he felt could be the first to depart, Savage replied: “I’ve said Julien Lopetegui. I think that given the quality of players that Wolves have lost and not replaced, they could really struggle.

"I hate seeing managers lose their jobs, because I listen to pundits on television who have never been involved in a football club – and everyone’s allowed an opinion of course – but when you’re involved in a club on a daily basis, I’ve come to learn about what happens behind the scenes a lot more.

“As a pundit, I don’t like saying that a manager should lose their job. There are loads of factors at play; who’s picking the players, the sporting director or another group of people?

"Does the manager get given the team selection and then has to be the head coach and get the best out of those players? There’s lot of variants why a manager might not be successful at a football club, but he is inevitably the one that will lose his job.”
