Wrexham manager Gary Mills believes loan-signing Mason Watkins-Clark has the attitude to succeed.
The 20-year-old Ireland under-21 international made his debut in the 3-1 friendly win over Bangor City.
"He wants to win, he wants to do things right and tells me he wants to come here and show what he's made of," said Mills.
"He's not afraid, he'll put his head in, he'll put his body on the line and you need that."
Watkins-Clark arrived from Stoke City on an initial one-month loan with an option to stay longer.
He is a full-back who can also play centre-half and in midfield, a versatility which could prove valuable, according to Mills.
The former Nottingham Forest defender added that the player would have to get used to the difference in physicality between age-group football and the senior game.
"He's come in now to a proper game from that under-21s stuff that he's used to, and you could see the scars on his legs," said Mills.
"That's the hard thing when you take a player in from the under-21 level, they're not used to what he's been playing in tonight [against Bangor City].
"That would have done him the world of good and would have opened his eyes, if nothing else, and said welcome to the real world."
Wrexham start their National League campaign away to Bromley on Saturday, 8 August.
