Martin Lipton believes Harry Redknapp will never manage another "big club" after taking the QPR job.
The Daily Mirror journalist was speaking on the Sunday Supplement after a dramatic 48 hours which saw Mark Hughes sacked by the Loftus Road club and replaced by the former Tottenham, Portsmouth and West Ham manager.
Redknapp, who was linked with a job as the national manager of the Ukraine this week, was at Old Trafford to see his side lose to Manchester United on Saturday and will take charge for their midweek clash with Sunderland.
But Lipton says that he had to lower his expectations after missing out on the England job and being sacked by Tottenham last summer.
"That's all he can get now," he told the Sunday Supplement.
"Once he left Spurs, that was it. That was his last go at a big club. What's bigger than Spurs? The clubs that are bigger than Spurs aren't going to appoint Harry Redknapp.
"Therefore he has to go down to the next tier and QPR, you could argue, are the tier below that even."
Redknapp took over Tottenham in 2008 when they were bottom of the table with just two points from their first eight games and guided them into the top five for three seasons in a row.
QPR are currently six points adrift of safety with 13 games gone and while Lipton feels Redknapp has the talent to keep them up, he says it's a much tougher job than he has faced previously.
He added: "He's a pretty good football manager, let's be honest.
"He took Spurs fourth-fifth-fourth for three years - the first time they've done that since Bill Nicholson was manager and he spent a lot of money, but he won the FA Cup with Portsmouth and he took West Ham to fifth.
"It's not as if he's got a track record of failure. Most of us thought he should have been the England manager and I've got no problems with admitting that I was one of those.
"Of course, he can do a job but he's got a harder task than he had at Tottenham because he's five games further into the season and two points better off, but they're rubbish."
