Both players have signed new three-and-a-half year contracts at the Reebok Stadium.
“I’m delighted to get the three young players on board,” Coyle told the club’s official website.
“It follows on from what we have done in securing the signatures of Fabrice Muamba, Chung-Yong Lee and Mark Davies on long contracts, building for the future of the club.
“To secure these three, who are supremely talented and have tremendous potential, is very pleasing.
“They are the kind of players who have caught the eyes of other clubs, and it is right that they should, so it’s important we made them Bolton Wanderers players for years to come.”
