Everton boss Roberto Martinez has insisted that the Toffees are not in the market to sell key players in January.
England midfielder Ross Barkley has been strongly linked with a move to Manchester City in recent weeks.
However, Martinez, whose side have lost their last four league games, remained unmoved when questioned on departures.
"This January window for us it is vital we concentrate on recapturing our best form so you can imagine all of our best performers, even if they get a lot of attention, they are not going to be anywhere," Martinez told reporters.
A recent report claimed that Everton would be willing to sell Barkley if they received an offer in the region of £45m.
