The Blades are now managed by former Toffee David Weir, with Stubbs suggesting that the two clubs could form a partnership.
"I think it's something that we will think about because it's a big club. Davey knows the young lads who could benefit the club and benefit him and, if that's the case, and we see if it's right for the player, then why not?" Stubbs told the club's official website.
"It will be a great experience for them, but first and foremost we will look and see if it's the right move for the player, because that's what we always do. We never send lads out on loan and just leave them.
"We see if it's the right type of club, whether they play the right type of football, whether it will suit them and whether they will look after the player. There are quite a few things we look into before we let the young lads out on loan."
Weir replaced Danny Wilson at the helm of United.
