Everton defender Yerry Mina is yet to make his debut after picking up an injury.
Mina has only recently returned to action at Everton, after picking up an injury.
The Colombian international is unlikely to be fit enough to start for the Toffees against Arsenal at the weekend.
But Silva insists that Mina is looking sharper and sharper by the training session now.
“Yerry Mina has had a full week working with the team. He is getting better every day,” Silva said at his latest press conference.
Mina’s return will be a welcome boost to Everton, as their defence has looked far from rock solid over the early part of the season.
Silva’s options in defence have been limited, and it has led to Mason Holgate and Kurt Zouma having to start together in recent weeks.
Everton were beaten 3-1 by West Ham United in their last match, after putting in a disappointing display, with Holgate and Zouma never looking comfortable.
Mina should offer steel to the Toffees’ backline though, and that could be crucial as they look to get back to winning ways in the coming weeks.
