Coyle said: "I look for players with energy and desire and if they are young so much the better.
"The three players mentioned come into that category. I want to freshen things up and add to an already talented group.
"There is no doubt Wilshere is a promising player and the situation about him maybe coming here is ongoing."
Bolton face Liverpool on Saturday on the back of a victory against Coyle's former club Burnley on Tuesday.
Coyle is pleased with the progress being made four matches into his stewardship.
He said: "We are trying to implement stuff in training which will be replicated in matches. I do not want us to be one-dimensional.
"I want us to have a few facets to our play. There was a lot of good football the other night. I was pleased with that but it is a work in progress. All the hard work is ahead of us."
