Port Vale boss Rob Page says his squad must match his own hunger for success if they are to carry the club forward.
Page has freshened up his playing staff this summer by making nine signings and is sure the competition for places will sharpen everyone's attitude.
"Everyone knows with the quality we have in the squad if they don't perform their position's in jeopardy," Page told BBC Radio Stoke.
"I want to win matches and need players around me with that same drive."
Page goes into Saturday's opening game of the League One season against neighbours Crewe with a number of selection decisions to make.

"It was a big blow to lose Chris but we want competition for places and everyone's had the chance to stake their claim in pre season.
"As a footballer, all I can worry about is performing at my best. If I am, I'll keep the jersey - if I take my foot off the pedal, I run the risk of losing my place.
"I've got to worry about winning games, for the club and my career - I want to be a successful manager and manage at the top level.
"To do that I need players who desire success - if they don't they're getting in the way of my being successful and taking the club forward."
