Chelsea are playing brilliantly, if they spend more time on the pitch they will outperform other teams. The only problem Chelsea will have that might end their chances of winning the Premier or doing well in all league is if they sometime in the future lack consistency. If the players should hold back even for a little then they might begin breaking into piece, right now we can see how midfielders are doing the work of defenders, including the forward like Joao Pedro helping out the defence, this is exactly what Chelsea need to keep in order to finish well.
Chelsea just needs to maintain consistency this season. They look to have started well this season and all of their games have been so well played this season except finishing the first match in a draw. They won the FIFA club world cup in an exceptional way, and I think they are going to have a good time in the champions league this season.
The champions league is yet to start, but with all indications, Chelsea are going to be amongst the teams that will be top contenders for the title. They just need to replicate the same tactics they used during the club World Cup in order to stand a good chance for the champions league title this season. I have some hope in them this season than I did last season.
