Sheffield United have completed the signing of Arsenal defender Auston Trusty.

The American moves to Bramall Lane for a mooted £5m fee. He has signed a four-year deal.

"I am more than excited. The opportunity to be here at this historic club, and an opportunity to play in the Premier League and show my ability, it is everything I could have ever dreamed of growing up as a kid. In Pennsylvania, this was a dream - almost an impossible dream but I believed in myself and the opportunity has come around, it is everything that I dreamed for," said Trusty.

"It is crazy how quick things happen in football. I have just come back from a US tour with Arsenal and a couple of days later I am sitting here doing this interview. Things did happen very quick, but that's how football works. I was really looking for an opportunity so as soon as it came about, things and details were ironed out. I am here, I wasn't wasting any time.

"Everything is coming to fruition for me. I am in the right place at the right time and in the right mindset. Everything has come together how I dreamed it."

Blades chief Paul Heckingbottom also told the club's website: "I'm delighted we've managed to get this one over the line, it is one of the positions we've been looking to fill and it is with one our own, a permanent transfer rather than a loan. He is at a good age to progress, he has experience having played at international level and in the Championship last year, where we monitored him and he picked up Birmingham's player of the year award. As a coaching team we feel that he has the athleticism and desire to succeed in the Premier League."
