Even though, for example, Chelsea can win in eight consecutive matches, but if the teams above it also win, then Chelsea's position will still be outside the European zone. Therefore, it is indeed impossible for Chelsea to rise to the top five, let alone for the top four it is clear that it is an impossible improvement.
It's hard to expect Chelsea to return to Europe next season because all the teams in the European zone are currently fully committed to defending their place. The league has entered the last 10 matches, so Chelsea will only bet on the odds even if they win the next 11/11 matches.
Chelsea only have to work on the Champions League, but of course their struggle will stop if Real Madrid is still able to maintain its dominance. Yes, I'm not going to underestimate Chelsea's chances, but that seems impossible this season in the Premier League.
Also, even though in the Champions League Chelsea made it to the quarter-finals but still, because the teams that are in the quarter-finals are top teams and also have good dominance in their respective leagues. So, the chance for Chelsea to qualify for the semifinals is clearly difficult to achieve.
Real Madrid are the favourites, I know that. But again, I'm not underestimating Chelsea's mission this season.
