Tim Sherwood says rookie left-back Lewis Kinsella has made a good impression with the seniors.
Sherwood has added Kinsella to the senior group in training at Bodymoor Heath.
The 20-year-old Watford-born defender has also been involved for the games against Newcastle and the Barclays Premier League and FA Cup matches with West Brom.
He has been drafted in on matchdays due to the injuries of recognised left-backs Aly Cissokho and Kieran Richardson.
But Sherwood insists Kinsella has made him take notice regardless.
He said: "Lewis has done well.
"He is a player you recognise on the pitch. He leaves someone sprawling out on the floor every time he's out there.
"For a young boy he's not shy.
"I know his name. Sometimes you see kids and I've been at the club for a year and I still don't know their name and they've trained with us 100 times.
"That isn't what I'm looking for."
Despite his rapid ascent, Sherwood says Kinsella may not be involved this weekend at Sunderland.
Kinsella picked up an injury in the U21 2-0 win at Bolton in midweek.
Sherwood joked that wasn't surprised by the fitness issue because of the plethora of problems in that area of the pitch.
He added: "Lewis got a kick in the U21s.
"He might be struggling. He's a defender - that's what happens."
