Aston Villa manager Martin O'Neill has found the center back he was looking for to solidify the team's shaky defense. Richard Dunne has completed a $9.7 million move from Manchester City. O'Neill believes Dunne has the character he needs following the retirement of the Danish defender Martin Laursen. "He is just the kind of person we are looking for," said O'Neill. Dunne will be joined by defender James Collins, who Villa will sign from West Ham for $8 million.
