Monk believes the target man is the most powerful forward in the Premier League and is not looking forward to the prospect of the 26-year-old visiting the Liberty Stadium later today.
The Swans have, however, been working on stopping Carroll in training.
"It's something we have to put right but he is an incredible player physically," the Swansea boss is quoted as saying by the Daily Mail.
"He is probably the most powerful forward in the Premier League and he has supremacy over everyone.
"Sometimes when the ball in is right, there's not much you can do but we have to try to stop him and that's something we've been working on."
Monk's claims, meanwhile, are backed up by one incredible statistic regarding the West Ham star:
|Team||Aerial Duels Won||Appearances||Minutes Played|
|Andy Carroll||West Ham||91||10||749|
|Mile Jedinak||C. Palace||83||18||1,617|
Indeed, as Opta stats show, Carroll has won the second-highest tally of aerial duels this Premier League season - despite playing just 749 minutes so far this term.
The West Ham striker has won 91 aerial duels, nine less than Stoke City striker Peter Crouch, who has played in eight more games.
Imagine how many Carroll would have had he been fit all season? The Swansea defence may be about to receive a little preview...
