Sheffield Wednesday have signed winger Adam Reach from Middlesbrough on a permanent deal.
Sky sources understand the fee to be £5m.
He told the club's website: "I'm really pleased. It's been a whirlwind day and I went into it not really knowing what was going to happen.
"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.
"Everyone knows what the club achieved last season and everyone knows what they want to achieve this season. I want to be part of that."
The 23-year-old has yet to figure for Boro this season following their return to the Premier League, and he spent last season on loan at Preston.
The England U20 international has made over 60 appearances for Middlesbrough but has also had loan spells at Darlington, Shrewsbury and Bradford.
