Yes they have a lot of players and have also brought in some good names too. Imo Chelsea will make the UCL. I’m so sure of this but they won’t win the league. They don’t have European distractions. Pochettino have given them a sense of play and they’re bonding and finding the rhythm this preseason. They will make the CL, people are underestimating what being totally out of Europe brings in term of squad's fitness. It's three teams that one can boldly say are ahead of them.
The results of pre-season matches cannot be used as a benchmark, now the Chelsea squad is filled with new players and there is no evidence that they will be much better and consistent.
I admit that Pochettino is an experienced and good coach in the Premier League, but what you have to remember is that the light in the Premier League is very tight, there are several teams that will compete hard to get to the top of the standings, and if you look at the player material that Chelsea currently have this makes me a little pessimistic.
Honestly pre-season matches shouldn't be the yardstick to determine the formidability of Chelsea in the upcoming season, recall that in most of the pre-season matches many Chelsea substitutes were tested or played in which when the league matches starts properly only the main squad selected by Pochettino will enjoy a regular playing time and majority of Chelsea first team squad are new signings thus it might take the team some period of time before they will adapt to the league consequently the team might have some mix results some wins, draws and some losses thus Pochettino should be given enough time and Chelsea fans should also exercise patience before the team will begin to be stronger.
