Chelsea have completed the signing of midfielder Romeo Lavia from Southampton in a £58million deal.
Reports claim the deal is worth an initial £53million plus £5million in add-ons.
The 19-year-old has signed a seven-year contract at Stamford Bridge after turning down a move to Liverpool earlier this month.
Lavia told the club’s official website: “I’m really happy join Chelsea and be a part of this exciting project. It’s an amazing football club with a great history and I’m really excited to get started.
“I can’t wait to meet all my new team-mates and build a chemistry together to achieve great things together.”
