Watch Croatia v Spain and Czech Republic v Turkey live on ITV
Mark Pougatch presents live coverage on ITV of Spain against Croatia in Bordeaux as the final round of matches in Group D take place. And over on ITV4, you can watch the other Group D decider live: Czech Republic v Turkey.
Defending European champions Spain have looked very impressive so far, with midfield genius Andres Iniesta pulling the strings in their two victories. But Croatia, with Luka Modric and Ivan Rakitic starring in their midfield, should pose the biggest test the Spanish have faced so far.
Czech Republic, meanwhile, will start as warm favourites against a Turkish outfit that has failed to shine at all.
Wales, winners of Group B, could yet face the third-placed team in Group D in the Round of 16: either Croatia, Czech Republic or Turkey could finish in third, but not Spain.
Coverage of both Group D deciders kicks off at 7.30pm on Tuesday 21st June, on ITV and ITV4. You can also watch both games
