Roy Hodgson has admitted that England cannot expect to enjoy as easier time of things against Estonia on Sunday as they did in their victory over San Marino.
The Three Lions travel to Tallinn to complete their Euro 2016 qualifying double header, which started with a comprehensive 5-0 triumph at Wembley on Thursday.
Hodgson acknowledges that his side should have enough to make it nine points from nine this campaign, but has warned that the Baltic state will not be pushovers in the sense that San Marino were.
"I would be a bit wary of putting Estonia in the same category as San Marino," he told reporters. "They might surprise people who haven't seen a lot of them.
"They're very Scandinavian in their approach, and you know how good the Swedes, Norwegians and Danes have been in terms of work ethic and organisation.
"It will be a bit of a test, but I'm very confident we'll see it through."
Estonia have three points from two Group E games thus far, having beaten Slovenia but lost to Lithuania.
