Stop moaning, they're under no obligation to field a strong team. They qualified based on their performances last season and can field any side they wish. If they have other priorities then they can choose to field a weakened side. Bolton 2 seasons ago reached the quarter finals playing their reserves, which is further than Depor have gone this season playing their strongest side. Since the 1990s teams have started to use their squads, and rotated accordingly. The teams that win the competition generally are those who know how to balance correctly to play across 3-4 competitions.
