Rafa Benitez has warned Mike Ashley that he cannot perform miracles every season and will only commit his future to Newcastle should the owner share his ambition.
The Magpies will replace Everton in ninth position with a fifth straight victory at Goodison Park on Monday night.
Benitez has comfortably renewed the club's top-flight status despite only being afforded a transfer budget of around £40million last summer.
The January loan additions of goalkeeper Martin Dubravka and Chelsea winger Kenedy have sparked their recent good form, but the manager says he will not settle for a mid-table return season on season.
