#2 Uncertainty surrounding key players
The new Premier League season begins on August 10th, and clubs are supposed to have had most of their transfer issues ironed out, with players staying already knowing their status and those leaving aware of the same. Most importantly, efforts are made to keep off interest for their important players.
At Chelsea however, that is far from the situation. Jorginho is the only major transfer arrival, while speculations are constantly linking their key players with moves away from the club.
Hazard has always been linked with a move to Real Madrid, and with Ronaldo's departure, those rumors now bear a bit more weight. Barcelona reportedly have Kante high on their list of most wanted players, while Willian's transfer was also negotiated with the Blaugrana before they signed Malcom.
New reports emanating indicate that Chelsea have accepted a £75m bid for Willian's sale from Manchester United and that the Brazilian is close to sealing a transfer.
With 11 days to go until the close of the transfer window in the Premier League, there might not be enough time for Chelsea to seek replacements for these very important players if they leave. Chelsea's lack of Champions League football also means that they would not be an ideal destination for world-class players.
Moreover, football is a psychological sport, needing as much mental fortitude as physical exertion to excel, and the players need to be in the right frame of mind to properly execute their duties as professionals.
These speculations don't do Chelsea's chances of success next season any good, as the players will be in a state of not knowing where they'll play next season, and with just 12 days to the commencement of the league, having your star players in such a state of mind is highly detrimental.
