Dyche said to Sky Sports: "Until I'm told different, there isn't any finance to go and change things. This is what we are. We changed the storyline last season, then in the summer we sell big players. You're trying to build a squad and the challenge starts again. It's a never-ending challenge at Everton Football Club.
"We finished strongly last season. We sell a player [Onana] who's growing and maturing and become a very important player. And then we bring in others who we've got to start the process with again and make them grow and mature and become important players. It's a cycle that keeps going and going and going."
