England and Croatia may not be close geographically but a rivalry has formed between the two nations over the years. The Three Lions have suffered heartbreak at the hands of them on a couple of occasions over the last 10 years, so this weekend Gareth Southgate's men will be desperate to inflict revenge.

Well on Sunday we face them again and despite the stakes not being as high as our previous meeting in Russia, it's still a must-win clash. The winners of this clash will progress through to the semi-finals of the inaugural UEFA Nations League, which take place next summer.
