Securing the futures of Ross Barkley, Seamus Coleman and James McCarthy is high on the agenda for the Spaniard, who hopes to see the trio continue to flourish at Goodison Park.
Barkley's performances in midfield have earned him an England call-up and the 20-year old is being tipped for a place in Roy Hodgson's squad for the FIFA World Cup in Brazil.
"We won't offer encouragement to any club over Seamus," said the Everton boss. "We are already thinking about Seamus, Ross and John Stones. We want to reward them, even James McCarthy.
"That is something we will look at this summer. They are players with long-term contracts.
"It is not a decision just to keep them at the club; it just highlights the next step of their development and rewards them for their performances.
"We hope they will feel excited about developing with the football club and they are footballers I believe to be of the highest, highest level."
