Maxwel Cornet became our fifth summer signing on Friday when he completed his move from Burnley to the Hammers.
The 25-year-old put pen-to-paper on a five-year deal, with an option for a further year, bolstering David Moyes' attacking options as we head into the new Premier League season.
Cornet was at London Stadium to sign his contract, pose for photographs and complete his media duties, as well as having a look around his new home.
Now you can go behind the scenes of his first day as a Hammer in the video player above!
