The Frenchman’s agent arrived in London on Wednesday morning to thrash out the final details of the deal taking him to Stamford Bridge on an 18-month deal for an undisclosed fee.
Sky Italy understands the deal is worth £15.3m with £2.2m in bonuses, however another source has told Sky Sports News the figure is £21m plus £3m in add-ons.
His move to Chelsea was confirmed hours after Arsenal completed a club-record transfer for Pierre-Emerick Aubameyang from Borussia Dortmund.
Speaking to Chelsea’s official website, Giroud said: “Chelsea is one of the biggest teams in the Premier League. They have won maybe the most trophies in the last six or seven years. It’s a massive club and I am proud to sign for Chelsea, and I’m looking forward to playing.”
Dortmund have signed Chelsea striker Michy Batshuayi on a season-long loan deal on Deadline Day as a direct replacement for Gabon international striker Aubameyang.
