Eddie Howe told Sky Sports Bournemouth's summer business will be their biggest yet as they look to improve for next season.
The Cherries are still on course for their record Premier League points tally after beating nine-man Tottenham on Saturday, but Howe said after full-time he felt the pressure to make sure next season went one step further.
He said: "I think it is a huge achievement [to be in the PL for another season], but the problem is that it gets boring for everybody here. Not the football, but the fact you stay in the Premier League is seen as the par for the course.
"I always think that when we achieve that, you're over-achieving to a degree with the resources and restrictions that we have.
"But we have some outstanding players at the same time and we're now having to try to push and push and push to try and improve, and it's going to be our biggest challenge to try and improve that.
"I think I've said it at the end of every season that we need to keep our best players. We've been able to do that to this point and this will be our biggest summer in terms of doing that.
"I'm confident that we can and it's really important that we do because we want to head the other way rather than lose the nucleus that we have."
