Jose Mourinho has suggested Everton should be targeting a top-four finish after spending £145m in the summer but the Merseyside club's manager, Ronald Koeman, says his Manchester United counterpart's claims are unrealistic.
Mourinho's comments came in his programme notes ahead of United's 4-0 thumping of Everton in the Premier League on Sunday.
Koeman, however, said his targets were unchanged from his debut season at the club when Everton finished seventh and that he needed more time before they could push for a top-four place.
"Is there anybody who sees this as realistic for Everton? Please, come on. Fans, press - we need time," Koeman said.
Everton are in the bottom three after losing three Premier League games in a row, conceding nine goals without reply. They also lost 3-0 to Italy's Atalanta in the Europa League last week.
"When you look at the fixtures at the start of the season, we knew we wouldn't win them all," added the Dutchman.
"We have played Manchester City, United and Chelsea away, plus Tottenham at home. Four title contenders, with the Europa League in between."
Everton's next league game is at home to Bournemouth, one spot below them in 19th, on Saturday.
