Fabio Capello says the England job is the most difficult in his career.
The England coach said: "This is my toughest job, understanding why this happens and solving the problem. This is the problem that all my predecessors have had. I'm hoping I will be able to understand why and rectify it.
And Capello, who was speaking at an event organised by England team sponsors Nationwide Building Society, insists that trying to make Premier League players into world beaters for the national team will be his last job in football.
He said: "I have enjoyed managing all the teams I've managed. I have great memories of my time at Roma, Juventus, Milan and Real Madrid. Each one of them has been a challenge. But I look at this as my last, my final challenge ."
Capello also concedes that there is a shortage of quality players on display in the Premier League, partly because of the influx of foreigners.
He said: "I can't perform miracles, these are the players we have and I can only call up the players we have. Creating new players is a long process, it takes a lot of time and you need talent to begin with. It's not going to be fast."
