Marcos Alonso is reportedly in London and is set to have a medical with Chelsea.
The Fiorentina left-back is poised to complete his move to Stamford Bridge tomorrow, according to the Mirror.
A £20m fee has been agreed between the two clubs, less than the reported £24m.
If the move goes through, Chelsea will be Alonso's third Premier League club after spells at Bolton and Sunderland.
Manchester United have sold striker Will Keane to Hull.
The United academy graduate joined the Tigers for a fee in the region of £1m and has signed a three-year contract.
Speaking about the deal, he said: “I’m delighted to move here.
“It’s a fresh start and a new challenge for me, so I’m really looking forward to getting things underway.”
Arsenal or Chelsea could make a late move for Borussia Dortmund striker Pierre-Emerick Aubameyang.
That is according to German football expert Lee Price, author of The Bundesliga Blueprint: How Germany Became the Home of Football.
He told Starsport: “Pierre-Emerick Aubameyang would be a huge loss to the Bundesliga - not just Dortmund.
“Chelsea and Arsenal are known admirers - and you can't rule out a late bid from one of those two over the next 24 hours. There's a genuine chance it could happen.
“Arsenal have brought in Lucas Perez but Aubameyang is a step up from that.
