Roberto Martinez has warned his Everton squad in the Daily Mail that their promising start to the season will count for nothing unless they pick up points in their next five games.
Everton face Premier League matches against Arsenal, Sunderland, West Ham United, Bournemouth and Aston Villa in the coming weeks.
And Martinez believes that unless the Toffees are able to show some consistency, they will undo all of their hard work over the campaign so far.
"The start of the season has been as challenging as we expected, but really, really good," he said.
"I think we have showed signs of a really interesting season ahead.
"But, now, the start of the season will mean nothing if we don't carry on with some consistency.
"I do feel this period until the next international break is a very important one for us."
Everton's start to the season has seen them beat Chelsea at home, while they also recorded an impressive victory away at Southampton.
The Toffees are currently sat in ninth place in the Premier League table, but their display in their most recent outing against Manchester United was poor.
Martinez's men were comfortably beaten 3-0 by the Red Devils, and they will be determined to put in a better showing this weekend when they travel to the Emirates.
Arsenal have been in fine form over the season so far, but Everton have a talented squad and they will be looking to showcase their quality by getting a positive result on Saturday evening.
