Everton centre-half Phil Jagielka recognises that the hard work starts now as England prepare to take on Poland in their next World Cup qualifier on Tuesday.
A 5-0 victory over minnows San Marino at Wembley was a nice tune-up for Roy Hodgson's men ahead of the midweek trip to Warsaw.
England are only too aware a trip to the Euro 2012 co-hosts represents a significant step up in calibre, and Everton defender Jagielka is grateful that Friday's match went relatively to plan.
"Three points in the bag, five goals scored and none conceded, as far as we're concerned it was a good professional job done," Jagielka said on Sky Sports News.
"We knew what kind of a test we were in for and we got through it okay - is probably about the right word - and we knew that Tuesday is probably going to be a lot more of a test.
"We're expecting a much more difficult game on Tuesday night."
Frank Lampard (calf) and Ryan Bertrand (illness) have both been ruled out of the game after failing to recover from the problems that also saw them miss out against San Marino.
The Chelsea duo's club team-mate Ashley Cole, meanwhile, finds himself at the centre of Hodgson's biggest selection call for Tuesday night, with club colleague Leighton Baines pushing him hard for the left-back berth.
Jagielka added: "It's going to be a really tough decision. You've got Ashley Cole on 98 caps, and probably the in-form player in the Premier League in Leighton Baines who's playing there at the moment.
"As far as the manager goes it's a headache, but probably a nice one to have. I think I'd be flicking a coin."
Baines turned in another impressive performance during the San Marino win and he has now started all four internationals since the Euro 2012 finals as Cole nurses an ankle problem.
Plenty of cover
On the absence of Lampard, Jagielka added that he expected Michael Carrick and Tom Cleverley to again shine if asked to deputise alongside returning captain Steven Gerrard.
"Frank's done well for England, especially recently, so we will be missing him," he said.
"But if you look at the other night's game, Michael and Tom did fantastically well and we've also got our captain to come back, so cover for Frank not being here is looking really good at the moment."
