The French striker was involved in the three-team swap between Borussia Dortmund, Arsenal and Chelsea.

Chelsea delayed the announcement a bit, but Olivier Giroud finally made the trip cross-town to join the Blues.

Arsenal signed Pierre-Emerick Aubameyang, making way for Borussia Dortmund to sign Michy Batshuayi on loan from the Blues. Giroud's purchase was the last link in this chain of transfers, and the French striker couldn't be more delighted to join Antonio Conte's team.

"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," the player stated to the team's website.

Here's how Chelsea welcomed their new striker on social media.

On the other hand, Arsenal's Twitter feed decided to bid farewell to Giroud after five and a half years with a couple of tweets. The Frenchman, who will join the Blues with an 18-month contract, scored 105 goals for the Gunners since he was acquired from Montpellier.

There were mixed reactions from fans and experts once the deal was made official. Have a look at some of them.
