Antonio moved to the Hammers from Nottingham Forest during the summer transfer window, and he has already seen the quality that Carroll possesses.
The pair linked up to devastating affect against Southampton in the Hammers' last match, with both players getting on the scoresheet.
West Ham had fallen behind against the Saints, but Antonio netted an equaliser before Carroll grabbed the winner.
And the powerful winger said: “He is a quality player. We know he will win the headers if we knock it up, we know if we hit it to the back stick he is going to be the man and score goals.
“He is one person we are confident if he is on the pitch that he will get goals.”
Although Carroll seems to have won over Antonio, he still has some work to do to convince all the supporters at Upton Park of his quality.
The England international has been inconsistent during his time at West Ham so far, with injury problems plaguing his progress.
Carroll could be set for a run of games in the first team over the coming weeks, if he does stay fit, as West Ham have a lack of options up front currently, and he will be hoping to build on his strike against Southampton.
