Everton defender Seamus Coleman says better standards in training has directly led to the improved results on the pitch.
Everton have made their best top flight start for many years and currently sit in fifth place in the Premier League going into the international break.
Coleman, who is on Republic of Ireland duty this weekend, has put the start down to an improvement off the field under new boss Ronald Koeman.
Coleman said: “It’s been good. We have had a disappointing two seasons, unfortunately. Finishing 11th isn’t where a team of our players should be.
“But the manager has come in and he’s worked hard, and I think you always get a reaction when a new manager comes in and just sets a few standards that should have happened in the previous campaign, by the players as well, just time-keeping and that, making sure people are in on time.
“They are little standards which should be the case, and it has just sharpened the place up all round. The lads on the pitch now know we have to perform or we won’t be in the team, and it’s just the way it should be, really.”
