Antonio, a £7million signing from Nottingham Forest in the summer, has barely featured under new Hammers boss Slaven Bilic.
But the powerful winger has finally been given a chance as a result of West Ham's crippling injury list, impressing after replacing Victor Moses in the 0-0 draw at Manchester United last time out.
The Hammers are experiencing what seems to be an annual glut of injuries to key players after losing star man Dimitri Payet, strike duo Enner Valencia and Diafra Sakho, playmaker Manuel Lanzini, Moses and now their best defender Winston Reid.
A fantastic start to the season saw the East Londoners sitting pretty in third place in the Premier League.
But Bilic's side have dropped down to seventh after failing to win any of their last five games.
Despite their dip in form, though, Antonio has told West Ham's official website he believes they can challenge for a top six place.
“We have not won for a couple of games now and we need to get three points back on the board again," Antonio told whufc.com.
“Even though we are picking up points in the league, which is obviously good, we need to be picking up victories to help us move higher in the league.”
You have to admire Antonio's ambition and he is right to be positive, particularly after finally breaking into the Hammers fold.
Crippling injury list
But any Premier League side would struggle with the number of injuries to key players that Bilic is currently contending with.
If West Ham can somehow navigate the next month or so reasonably well they will be in a good position to kick on and perhaps prove Antonio right in the new year as their walking wounded start to return from their respective lay-offs.
The Hammers entertain in-form Stoke City at the Boleyn Ground on Saturday knowing a win would put them level on points with their rivals Tottenham Hotspur in fifth place.
