A draw against Slovakia will be enough for Spain to progress to the European Championship’s round of 16 as long as Poland fail to win against Sweden.
The results in groups B and C on Monday have left both Finland and Ukraine on three points each but with negative goal difference.
That would mean Spain – with a draw – would finish on three points but their three draws would leave them with a goal difference of zero.
A Poland win, though, would put them onto four points and leave Spain bottom of the group should La Roja not win.
