United's kids such as Ryan Gauld and John Souttar have been the centre of much attention already this season but McNamara is not fretting at the prospect of his men being linked with moves elsewhere in January.
He does concede, though, that he will be happier when the transfer window closes again.
McNamara said: "It's part of the game these days. You can't get away from it.
"There will be more of it in the next few weeks so I'll be happy when the window shuts.
"As far as I'm concerned, it's important that we keep them all so they can continue to learn their trade here.
"I was very happy with the response shown by the players here as they showed a lot of spirit.
"It was always going to be a difficult match against Hibs and we had to fight very hard for a draw."
