Lookman spent the second half of last season on loan at Bundesliga outfit RB Leipzig, who are keen to make the move permanent after the 20-year-old scored five goals in 11 games.
The youngster is also understood to be open to a move as he looks for more regular first-team football, but Silva has insisted that Lookman is in his plans for the upcoming season.
"Of course he is in my plans. He is an important player for us, he is a good player with good talent," Silva told reporters.
"He went on loan and improved and was happy there and now is our moment to make him happy here and to improve his qualities as he is our present and future."
Lookman joined Everton in January 2017 and has since made 24 first-team appearances for the club across all competitions, scoring three goals.
