Henderson has been asked to play wide-midfield, wing-back and in the central-midfield role in the nine games of the campaign so far.
"Jordan has been outstanding in all the games," Marsh told Liverpoolfc.com.
"He's able to play anywhere across the line and he's played wing-back on occasions. His attitude and enthusiasm for the game is there for all to see.
"His technical and tactical qualities have shone through. He's been excellent.
"He's settled into the position really well. When he plays in the central midfield role, he's more tactically aware and when he plays in the wide role, he provides the energy up and down the lines. He's got lots of strings to his bow.
"Jordan got off to a difficult start, which is tough when you come into a club like Liverpool. But he's found his feet after that settling-in period."
