Carroll, 28, passed a medical on Tuesday and once his free transfer was completed Alan Pardew spoke to the official site “The injury to Jimmy Walker in the Play-off Final was a real hammer blow for us and I’ve moved quickly to rectify that situation by signing Roy Carroll, who is an established Premiership goalkeeper.
“
“I believe Roy’s best years are ahead of him and when a club is re-introduced to the Premier League, as we are, goalkeeper is an essential position.
“
“This will be the first of what I hope will be three or four more signings to strengthen the team for the challenge ahead.”
