About the not busy schedule is of course interesting, except that previously many teams in the English premier league complained that even without European league games the schedule of games in the league is very tight, that it's hard to cope with it, etc. Those who will play in European tournaments next season have their own problems, while Chelsea should try to recover in the meantime. It's unlikely they'll make it at least to the Europa League, but it's worth a try.
Several Premier League team coaches complained about the very busy schedule of matches, even Pep Guardiola also complained about this season's schedule when they still had the chance to win the treble winner. So it has become commonplace for Premier League teams, but maybe going forward it needs adjustments to make it even better for all teams.
Chelsea is a team that has been discussed a lot since Pochettino was appointed as coach. But are you sure Pochettino is the right coach to bring Chelsea back into the top 4? I'm still not very sure about his abilities, but he is an experienced coach in the Premier League with Tottenham in previous seasons.
