So who would have thought it? After Thursday's last-gasp winner from Daniel Sturridge, it looked like England would top the group, with Wales' future in the competition hanging in the balance.

Predictably, Twitter was its usual entertaining self - here are the highlights (and lowlights) of the final game of the group stage for England and Wales.
