Plymouth Argyle manager Derek Adams has praised the impact of midfielder Graham Carey on his squad.
Carey scored his eighth goal this term in the 2-1 win at York City as Plymouth kept their five-point League Two lead.
"Graham Carey was absolutely outstanding," Adams told BBC Devon.
"He was involved in a lot of the good work, he was unfortunate not to have scored more. He's created a number of opportunities and his all-round performance was top class."
Carey joined Argyle on a one-year deal in the summer.
"He is a top player, I've signed him three times now and he's really done the business," added former Ross County manager, Adams.
But the Plymouth boss was coy when asked if he would try and persuade Carey to sign a new deal, saying: "We'll have to sit down and talk to people in the future."
Carey is able to talk to other clubs in January as he will have less than six months remaining on his deal.
