England fans recovering from Friday night's victory celebrations in Kiev were confident that Roy Hodgson's side would reach the knockout stage of Euro 2012.
After the vital 3-2 come-back win against Sweden, the Three Lions need just one point against tournament co-hosts Ukraine on Tuesday to reach the quarter finals.
But the possibility of then playing Spain has left some fans predicting that could spell the end of England's run in the competition.
Ian Saville, 43, from Crawley, West Sussex, said: "I can see us getting a victory against Ukraine. I think it will be a tight match but I think we'll win 2-1.
"We need to win the group because if we go through as runners-up and we hit Spain in the quarter finals I think it will be a reasonably early exit."
Darren Butcher, 34, from central London, said: "We'll get out of the group but I don't fancy us to get past the quarters. Just because we've beaten Sweden doesn't mean we're going to win it."
England fans chanted "We're not going home!" as they left the Olympic Stadium last night.
A spokeswoman for the Association of Chief Police Officers, which is leading the contingent of British police at Euro 2012, said there were no incidents of disorder involving England fans.
Many supporters struggled to recall an England game at a tournament that contained as many ups and downs as last night's thriller.
Vinny Goodfield, 34 from Bournemouth, said: "It was typical England going to pieces, but we got the three points.
"It's a lot of years since we've had a win as exciting as that."
Chris Holloway, 51, from Bristol, said: "It was on a knife-edge. I can't remember a big game like that before."
Newcastle supporter Gary Leonard, 47, said fans "celebrated like we had won the cup" when Danny Welbeck flicked in the winning goal.
"We couldn't believe it," he added.
England supporters now face a 450-mile journey to the industrial city of Donetsk for their final group match.
