Frankly speaking, the Conference League, the top 4 in the Premier League and first place in the Club World Cup are not the achievements that can be called incredible or prove anything. According to bookmakers, Chelsea will face the same fight for the top 4 next season, they are not in the pool of title contenders and no one will be surprised if their next season is less successful than the last one. For example, due to the fact that in addition to the Premier League they will have to concentrate on the Champions League (which takes away more energy than the Conference League).
Let’s see then because you’ve made a good point concerning their participation in the champions league next season which they didn’t in the just concluded season. They will face bigger teams and face more competitive football than they faced last season in the conference league. They have shown a good performance from last season till now and there is no doubt that they’ve improved very well. Next season is another test of challenge to them to prove how strong and dominant they can be in the competition next season while holding on to their World Cup title which they earned with their strength and quality as a team.
