Sheffield Wednesday have beaten off competition from other Championship clubs to sign Adam Reach from Middlesbrough.
Reach, 23, spent last season on loan at Preston North End, and was a key player in the Boro team which lost the Championship playoff final to Norwich in 2014-15.
The left-winger, who has signed a five-year contract at Hillsborough, moved for a substantial undisclosed fee.
"I'm really pleased. It's been a whirlwind day and I went into it not really knowing what was going to happen," he told Wednesday's official website. "I trained with Boro and then as soon as I was told of the interest from Sheffield Wednesday, I wanted to get straight down here.
