Cotterill brings in defender Foster
Burnley have signed Crewe defender Stephen Foster on a two-year deal.
The 25-year-old centre-back has snubbed a new deal from the Alex, who were relegated to League One, and also held talks with Barnsley.
Meanwhile Crewe defender Chris McCready has turned down the offer of a new deal and has left the club.
The 24-year-old made his Alex debut in 2000 although he struggled with a number of injuries in the following season.
