Boro have agreed a deal to sign United States international goalkeeper Brad Guzan.

Guzan, who was with Aston Villa last season, becomes Aitor Karanka's eighth senior signing of the summer and has agreed a two-year deal with the club.

The 31-year-old made 34 appearances for Villa last season and played every game for Jurgen Klinsmann's USA squad in the summer as they reached the Copa America semi-final.

He brings a wealth of Premier League experience to bolster Boro's goalkeeper options further, having spent seven seasons at Villa Park.
