Nathan Thomas will undergo a medical at Sheffield United on Saturday morning, according to Sky sources
The 22-year-old has agreed personal terms with the League One champions, after a fee of £300,000 was agreed with current club Hartlepool on Wednesday.
Middlesbrough had agreed a similar fee for the player, but Sky sources understand Thomas chose United because he felt it would be better for his career.
The winger scored nine times in 34 appearances for relegated League Two side Hartlepool this season.
