They need squad depth.

And they are focusing on English players because they are a bit out of whack with the FA (or I should say they are up against the limits of homegrown players).

It's why they are going after Ox, Barkley and Drinkwater.

None of them are expected to start, but Chelsea has 7 matches in September and are alarmingly thin (red cards and injuries have exposed this early).

The starting 11 is fine


Morata
Hazard-Willian
Kante-Fabregas
Alonso-Moses
Cahill-Luiz-Azpilicueta
Courtois

It's the depth behind them that his the problem:
Batshuayi
Pedro-Kenedy-Musonda
Bakayoko
Rudiger-Christensen
Caballero-Eduardo


They need more cover other than Batshuayi. It's why they are still making offers being linked to
Belotti and Llorente
Ox, Drinkwater and Mahrez


We shall see what the coming days bring, but I don't expect big name starting XI type players to head to Stamford Bridge. They need squad depth.

Otherwise that squad looks pretty deep to me other than at forward.

Chelsea seems to be in on lots of players at the end here too. I expect they'll be fine.

But all indications are another season on loan. I included him because he hasn't actually been loaned out as of yet (Newcastle is the latest rumor).
