The Athletic reported that Chelsea believed their roster had improved greatly and the players who left the team had been replaced.
The two wingers, Sancho and Maduaike, who left the team, have been replaced by Gittens and Estewan. With the arrival of Drapp and Joao Pedro, the front line has also been strengthened.
In addition, the addition of Essugo and Andre Santos, who returned from Strasbourg on loan, provide additional midfield depth.
Signing Harto also fills a major vacancy in the roster, as Cucurella has a substitute for that position instead of having right-back Gusto or Rees James come in the cameo.
