The US international has left Aston Villa on a free transfer to return to the Premier League with Aitor Karanka's promoted outfit.

Middlesbrough confirmed the signing of Aston Villa goalkeeper Brad Guzan on Friday, increasing the competition for places in that position at the Riverside Stadium, and supporters of both clubs took to Twitter to discuss the deal.

It brings to an end the US international's eight-year stay at Villa Park, after first arriving in 2008 from Californian club Chivas.

Guzan was already turning out for his national team when he moved to the Premier League, but his initial seasons in the UK saw him playing backup to veteran US star Brad Freidel. Guzan finally got a serious chance as first choice not long after Friedel moved to Spurs, ousting Shay Given from between the sticks.

His four years as number one have seen wonder saves as well as bouts of poor form, but there is no doubt that when he is on his game the 31-year-old is an outstanding shot stopper.

Villa have already signed Italian prospect Pierluigi Gollini this summer, and with Roberto Di Matteo looking for further additions in that position, Guzan has moved to Teesside to continue his career.

It won't be much easier to earn first team football at the Boro though, with Victor Valdes arriving as first choice for the club's return to the top flight. The American will battle Dimi Konstantopoulos and Tomas Mejias for a place on the bench, and perhaps a role in the domestic cups.

Villa and Middlesbrough fans gave their rather opposing thoughts on the player's departure/arrival on Twitter following confirmation of the deal:
