Everton manager Roberto Martinez has claimed that Manchester United's bid for Leighton Baines and Marouane Fellaini was a "waste of time".
The Premier League champions made a combined offer of £28m for the pair on Monday.
However, the Toffees were quick to issue a statement describing the bid as "derisory and insulting".
"It's been well-documented what happened with the transfer speculation," Sky Sports News quotes Martinez as saying.
"That's been dealt with and it was all a little bit of a waste of time, time I don't want the players to waste."
United are expected to return with an improved offer for the duo before the end of the transfer window.
