indeed both chelsea and liverpool not play in european competition even chelsea now compete in BPL only.
but i think it is not guarantee anything manchester united at same position in last two season and what happened to them? nothing.
it may can be an advantage on how player fitness and avoid a lot of injury .
Man United was not being on top performance in last two seasons, in otherwise Chelsea and Liverpool playing great in this season. So if you look the difference, then you will realize that both of teams have good chance to win Premier League now.
Yeah. The clubs that would hurt this the most would be Arsenal and Tottenham. They do not want those two clubs you mentioned to do well because it would diminish the chances of either one of Arsenal or Tottenham to be in the top four. Man City is threatned too, but not as much imho. And imagine if Man United really is performing with their group of players, my god. Tottenham would be the first to be out of top four.
