Sam Allardyce has told his Everton squad they must take their chances when they arrive as the Blues bid to get back to winning ways.
The Toffees have been unlucky with injuries so far this term, with James McCarthy the latest enforced absentee after breaking his leg against West Brom on Saturday.
While injuries have opened the door for others, Allardyce has spoken to players who have not been first-team regulars and said they must be "super fit" and "super dedicated" when they are called on to don the royal blue jersey.
Allardyce, who last week reached 1,000 competitive games in management, enjoyed a fine start at the Goodison helm, becoming the first Everton boss to avoid defeat in his first seven matches in a spell that saw the team concede just two goals.
The Blues have endured a tricky spell since the hectic Christmas schedule, with Allardyce calling on those wishing to show what they can do to take any opportunities they are given.
“I say to players not in the team or squad, 'If you let yourself go, you do yourself the biggest disservice you possibly could, because when needed you will not be able to perform’,” he said.
“When you cannot perform, you get one chance – if you blow that chance you do not get another, not at this level now.
“You have to keep yourself super fit, super dedicated – because all the players doing the work on a matchday are keeping themselves at the highest level of fitness they can.
“If the lads not in the squad do not keep themselves right up there by doing the extra work they need to take that chance when it comes along, they end up failing and having no other chances – because when they have had the opportunity they failed to show the potential and ability they had before they came here.”
Everton are next in action when they welcome Leicester City to Goodison Park on Wednesday 31 January, kick-off 7.45pm.
