Eric dier disappointed by englands world cup defeat to belgium

I think you may be mistaken. Eric Dier is an English professional footballer who plays for Tottenham Hotspur and the England national team. While he has played in several important matches for England, including the 2018 FIFA World Cup, I couldn't find any evidence of him expressing disappointment about a defeat to Belgium.

In fact, England's match against Belgium at the 2018 World Cup was a 1-0 defeat, but it was a group stage match, and England went on to finish fourth in the tournament. Eric Dier played in that match and was part of the England team that ultimately finished fourth in the tournament.

If you're thinking of a specific quote or interview where Eric Dier expressed disappointment about a match, I'd be happy to try and help you find it.
