Everton manager Marco Silva wants Richarlison and Yerry Mina to improve their English skills.

The duo are important players for Silva, and he believes their inability to speak fluent English is impeding his team.

Asked about Richarlison's progress, Silva said: "No, it is not as good as I'd like.

"But he's trying every day. Mina also.

"This is something we demand from them because this is one of the keys for them to adapt faster and to understand everything."
