The Albion boss was speaking after signing Carson on a four year deal for a fee of £3.25 million.
"I think he's been looking for some stability in his career after spending a lot of his time as a Liverpool player out on loan at other clubs," the Albion boss has said.
"We're delighted he has decided to make the Albion his permanent home. Scott is one of a group of very talented, emerging, young English goalkeepers.
"Hopefully, we can provide him with a platform to push his career onwards and upwards."
