Sheffield United boss Chris Wilder says they're keeping tabs on the progress of their youngsters away on-loan.

Wilder says they don't loan out players for the sake of it.

He explained, "There's a loans manager who keeps us up-to-date, there is contact with the club, footage and as you can imagine we get coverage of every game. There is also talk from staff to staff.

"They are not just out there and forgotten about.

"They are out there to play well and be their best players.

"If Rhys (Norrington-Davies), for example, wants to play in the Premier League or play for Sheffield United, he has to be one of Luton's best players.

"He understands that and we keep track of that through our scouting situation and contacts that we have in the game.

"We will monitor his progress, he has done great and we will assess it at the end of the season what we do and where he goes with it."
