Roberto Martinez has reassured Everton's supporters that the club will not be selling any of their "top performers" during the January transfer window.
Reports surfaced in December that Manchester United were preparing a £50m bid for midfielder Ross Barkley, while the Red Devils have again been linked with a move for Leighton Baines.
However, Martinez has now spoken out to deny those rumours.
"We've attracted a lot of attention with the performances of our players but I can tell everybody that you can be very, very assured that we are not going to lose any of the top performers that we have this season," he is quoted as saying by the Daily Mail.
"That for me is the priority - not to lose any of the dynamics."
The Toffees boss also confirmed that he could add to his squad with a couple of "very specific players".
"Maybe we'll bring one, two, very specific players that are going to help the ones we have," he added.
Everton are fifth in the Premier League table.
