England has not yet secured additional spot. They still need one more win in the quarter final to secure five spots in UCL next season. I'm not expecting Arsenal or Villa to do that. However, this win can come from Chelsea. This is because it doesn't matter on what competition it is. As long as one of PL club win quater final, additional spot can be secured.
It seems to me City and Chelsea will be playing at UCL next season if PL gets 5 UCL slots. I hope it will be coming true.
Obviously Chelsea is going further than the quarter finals of the conference league and for Aston Vila and arsenal that will b facing Both PSG and real Madrid respectively, we can't just write them off and assume that they don't stand a chance against this two teams. Arsenal vs real Madrid game is going to be a tough game that we can't just assume that real Madrid will easily win arsenal, arsenal as a team are fighters even though they are usually unlucky with trophies but in terms of play, they have all it takes to proceed further in their champions league journey even though they are facing the almighty real Madrid.
An additional one champions league spot for the English side will be a good thing because a lot of the teams that are even among the top six best team in the premier league are still very much good and worthy of participating in the champions League. If it eventually works, the way the premier League table his will just be the perfect way to see the league come to an end so Manchester City and Chelsea that where quite good for this season can get a chance in next seasons champions League
