Richarlison did not participate in the whole of Everton’s training session this morning, as he underwent some individual work.
The Brazilian has picked up a knock, and Silva admits that it is doubtful whether the in-form forward will be picked.
“He didn’t do the whole session today. He did some individual work,” Silva said.
“He’s still in doubt for the match. Nothing changed yesterday for today, let’s see how he will react after the work he did this morning.”
If Richarlison does miss out on playing for Everton against Chelsea, it will be a major blow for Silva’s side.
The youngster has been Everton’s biggest goalscoring threat this season, and has led the line well in recent weeks.
Richarlison scored twice for Everton last weekend, as the Toffees beat Brighton & Hove Albion.
If Richarlison does miss out on playing against Chelsea then it could provide Cenk Tosun or Oumar Niasse with the chance to start up-front.
