Middlesbrough sign Aston Villa goalkeeper Brad Guzan

Aston Villa's goalkeeper Brad Guzan has completed his move to Middlesbrough, the club have announced.

The United States international has agreed a two-year contract with the Teessiders.

Guzan made 34 appearances for relegated Villa last season and played every match in the USA's run to the Copa America semi-final.

The 31-year-old is likely to be back-up at Boro to former Barcelona and Spain goalkeeper Victor Valdes, who joined the newly-promoted Premier League club earlier this month.
