Williamson signs for Sheffield Utd

There had been speculation linking him to Birmingham City but he agreed a three year deal with Kevin Blackwell's side after passing a medical.

Blackwell told BBC Radio Sheffield: "Williamson has got great athletic ability to get from box to box.

"Once we knew we could get him we were delighted to sign him."

Williamson made 78 appearances for Watford in his time at Vicarage Rd.
