Chelsea have agreed a fee of around £30m for Kiernan Dewsbury Hall, according to several reliable sources including David Ornstein and Fabrizio Romano.
Dewsbury Hall will join Chelsea after the completion of his medical this afternoon.
He joins his former manager Enzo Maresca in making the way to Chelsea.
Maresca was understood to not have demanded this signing but is very happy that he is going to be re-United with his star midfielder.
Dewsbury Hall scored 12 goals last season and assisted 14 times.
