The duo have been linked with Manchester United, Liverpool and Arsenal.
“You have to look at each deal individually,” said Lennon. “With McGeady, we felt the timing was right and the offer was right. With some of these guys who have just come in the door, as the chairman says, if the timing’s right we’ll maybe look to cash in on it.
“But with these guys, even in the summer, the timing might not be right. We’re building a team here and it might be difficult to replace these players.
“I would be surprised if we need to sell in the summer. I haven’t sat down with Peter (Lawwell) or anyone from the board on that aspect of things – but any offers that do come in will be treated with hostility.
“The Utopian idea is to create a team that can dominate for four or five years. You want to put a team on the pitch that can win games consistently and who can do it playing good football. It’s not often you get both but in the last six or seven weeks we’ve done that.”
