Silva is reportedly keen on leaving the King Power, having made just one league start this season.
A number of clubs are interested in the midfielder, but Puel does not want him to leave.
"I'm happy for Adrien (Silva) because he can give other attributes and possibilities for the team," Puel said.
"For Adrien, Mendy and Ndidi, we can play three in midfield and I think it will be an opportunity for Adrien (Silva) to have an opportunity in the second part of the season.
"We will see because it's the end of the transfer window but for me, we have good balance and a good squad."
