Brentford have agreed a £2.8m deal with Fiorentina to sign Danish midfielder Christian Norgaard, Sky Sports News understands.
The 25-year-old signed for Brondby when current Brentford boss Thomas Frank was in charge at the Danish club in 2013.
Norgaard made the switch to Fiorentina last summer but the move to Italy has not worked out for him and he is set to resume working with Frank at Griffin Park.
The midfielder also had a spell at Hamburg earlier in his career.
He has represented Denmark at youth level, but is yet to earn a full cap for his country.
