Chelsea have a good squad, but they need to play together in harmony and get to know each other for a while. Look at Manchester City a few years ago; they dominated the Premier League on their own after being in harmony. To achieve the same, the players will need to play together for a while and get to know each other. Perhaps Chelsea could be one of the favorites next year, depending on how well the players can find each other.
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
necessarily need to keep in order to finish well.
