Hammers hero Dimitri Payet has been getting all the headlines this season and rightly so.
But Antonio is coming up on the rails and right into contention for the club's prestigious Hammer of the Year award, an honour given extra significance by the fact it is the club's last ever season at their home of 112 years.
Antonio is adored by supporters for his guts, graft, determination, superb attitude, power, pace, energy, stamina and goals - including the crucial strikes in back-to-back 1-0 home wins over Sunderland and fierce rivals Tottenham Hotspur.
The flying winger has even made filling in at right back look easy and has been tipped for England honours.
While his form, goals and versatility have been catching the eye so too have his celebrations.
Do the Homer
After netting the winner against Sunderland Antonio took off towards the corner flag and pleaded for space from his onrushing teammates before dropping to the floor, rolling on his side and recreating Homer's celebratory rotating dance from the Simpson's Movie.
The celebration grabbed the headlines and the player later revealed he was inspired after watching the film with his children in the run-up to the game.
The Fresh Prince of the Boleyn
Then when Antonio struck again against Spurs he took off to the opposite corner to celebrate with the provider of his goal Payet before reenacting some TV gold.
While Hammers fans were doing jigs of their own on the terraces, Antonio decided to break out into another dance this time copying Carlton Banks' (Alfonso Ribeiro) famous routine from the hit 90s TV show The Fresh Prince of Bel-Air.
This clip is set to House of Pain's Jump Around whereas Carlton used to boogie to Tom Jones but Antonio is definitely taking up the US star in his latest celebration.
Grafter and The Beast are just two of the nicknames already bestowed on Antonio from the terraces, a sure sign that supporters haven taken him to their hearts.
But what could be his next celebration? We've suggested some below, but have your say in our poll.
