England manager Roy Hodgson got it badly wrong on Monday night as his team failed to break down a stubborn Slovakia defence in Saint-Etienne.
Hodgson made six changes to the side that defeated Wales on Thursday afternoon and paid the penalty to finish second in the group.
In contrast, Wales kept their strongest team and went on to batter Russia 3-0 in Toulouse to take top spot. Goals from Aaron Ramsey, Neil Taylor and the ever-impressive Gareth Bale made sure the Welsh secured a potentially much easier path to the semi-finals.
Prior to Monday's action, Belgium thrashed Ireland 3-0 in Group E on Saturday to book their place in the next phase, whilst Group F hangs in the balance following draws between Iceland and Hungary and Portugal and Austria.
Whoever tops Group F, currently Hungary, will then play England in the next round on Monday.
Sunday saw Albania give themselves a third place lifeline with a 1-0 victory over Romania thanks to Armando Sadiku, whilst France and Switzerland played out a draw that sees them both sail through to the last 16.
Hosts and one of the favourites for the tournament, France are on course to meet England in the quarter-finals in Paris should both sides make it through their respective matches in the coming days.
