Belgium were good today, but they had no meaningful opposition. This Irish team is desperately short of technical quality.
Dembele going off injured should be a concern to Belgium. If he or De Bruyne don't play then I don't see them going a long way in the tournament.
Bringing Moussa Dembele back in and taking Marouane Fellaini out can surely only benefit Belgium. You saw what happened to Spurs at the end of the season when Dembele was suspended.
