Manchester United? They'll even finish top four if they can take every game seriously like the Champions League finals. Wow, you're writing all three recently promoted side off? How about Brentford?! I'm certain they'll be relegated. They have lost their manager and now key players are being drawn out. I don't know it all but they're my pick to be relegated next season. Sunderland moving ambitions though 
It seems that Brentford are without direction, they even signed Jordan Henderson, 35 years old, who comes from Ajax

I don't expect much from Brentford, but they still have some players who remained in the team. The biggest problem could be that the coach can't manage the team well, and in my opinion, he's off to a bad start when he makes this signing. I could be wrong, but it seems to me that Brentford has a high risk of being relegated. Maybe this coach won't be able to finish the season without being fired.
It's not yet time to judge when the Premier League hasn't even started yet, and will Chelsea be as good as before, or even better? No one knows, but what clear is that with the recruitment they've made in this summer transfer window, I believe they haven't made as many mistakes as in previous transfer windows and are certainly only buying the best quality players, such as Joao Pedro, who was one of the best recruits because he immediately performed brilliantly in his debut with Chelsea in the Club World Cup yesterday. Perhaps with this, they will improve their performance in the Premier League later.
Chelsea is one of the teams to watch out for since 2 years ago I said this several times because we know they are trying to build a solid squad with a huge budget and the result? Chelsea finished in 4th place + 1 Europa League Trophy and reach the CWC final of course this achievement should not be ignored. Despite their success last season but for next season we can say anything because competitors are also doing the same thing by recruiting new players and we can say this is one of the aggressive transfer windows for Premier League teams.
Previously I have posted a list of EPL teams' spending in the transfer window and Chelsea still holds the record for the highest spending so with this, Chelsea's next target is not only to finish in the top 4 but of course to race for the title.
Club World Cup matches are very different from Premier League matches. Last season, Manchester City was weak, but I believe they will be better this season. Liverpool still has the same squad, but with some improvements. So, in my opinion, it will be difficult for Chelsea to win the Premier League.
