Everton manager Roberto Martinez claims there is no temptation to sell Marouane Fellaini and Leighton Baines as they brace themselves for further interest from Manchester United.
Everton this week dismissed a £28million offer for the highly-rated pair from Old Trafford as "derisory and insulting".
It remains to be seen whether United, now managed by former Toffees boss David Moyes, make an improved bid but Martinez has stressed it would not be welcomed.
The Spaniard said: "There is no temptation. In football you want to keep your best performers and that is where we are.
"You always get into a debate when there is a club that matches the valuation of a player. Then you need to make a decision.
"That has never been the case and where we are is we want to keep out most influential players and build from that.
"It has been well reported what the approach has been. We take it as a football compliment and move on. Now the focus has to be the games."
Several managers in the Barclays Premier League have expressed their frustration that the summer transfer window remains open after the start of the season.
There have been calls for it to close before the first game but that would not mirror the situation in other European leagues.
Newcastle boss Alan Pardew was particularly angry after Arsenal submitted a bid for his player Yohan Cabaye hours before Monday's game at Manchester City.
