Chelsea need to be much more active in the transfer market now. They even need to be the most active team among the top teams of the league. Because they have parted ways with many players in this transfer window. They will need to replace them with solid alternatives as soon as possible. They are in a rebuilding process in short.
Nope, they don't need to be active in the transfer market right now because
there's already a possible line up for the next season.
The last season Potter sign so many players and Chelsea squad can be used for 3 teams to be honest, even though they recently have sold many of their players, it doesn't hurt them because they still have many players.
