Sven-Goran Erikkson believes it is far too early to label Fabio Capello's reign as England coach a success and the Italian should only be judged at the World Cup.
Capello has been lavished with praise since he took over in December 2007 and booked the nation's place in South Africa with eight straight qualifying wins.
But, after his 100 per cent record in competitive games came to a halt on Saturday, Eriksson said: "When it comes to qualifying, England should be up there. He's a good manager, no doubt. But the big test is the World Cup."
Eriksson, who took England to World Cup quarter-finals in 2002 and 06, added: "There will always be mistakes. Even if you're a good team you can never be perfect."
Eriksson also feels England are still too reliant on striker Wayne Rooney, who has scored nine goals to help England top Group Six but will be missing with injury against Belarus on Wednesday.
The Swede added: "Let's hope he doesn't get injured next summer because he is extremely important for England."
