The Hammers take on Blackburn Rovers in the fifth round on Sunday.
The Hammers are currently sixth in the Premier League table at this moment in time, level on points with Southampton in sixth and just a point behind Manchester United in fifth.
They are also set to take on Championship side Blackburn Rovers in the FA Cup fifth round on Sunday, having managed to overcome Liverpool with a last gasp winner in the last round.
Manager Slaven Bilic may have to choose which he will target at some point, and when asked his opinion, Antonio says he would sacrifice the league for FA Cup glory.
“I’d go FA Cup over a top six finish,” he told whufc.com.
“It’s one of those things where you don’t get remembered for coming sixth, but if you win the FA Cup everyone remembers that, you have a medal to show for the rest of your life.”
“As a kid you always dream of playing in it and as a player you always dream to win it.”
Bilic’s side will be confident of winning the FA Cup this season as well given how the draw panned out.
While they managed to draw a Championship side, and one fighting to push away from the relegation zone at that, several Premier League sides will all meet each other, opening the path to the final further for the Hammers.
Winning it would certainly be welcome as well, with them keen to bring success to Upton Park one last time before they bid the famous old ground farewell in the summer.
