Monk said of De Guzman: "He epitomised everything that was good about us today - his movement, his desire to get the ball back when we lost it.
"It would be an important signing for the club, but you obviously have to speak to the player and see how he feels as well."
Of the skills top-scorer Bony showed, Monk said: "For me, it was great for the crowd to see. That's why I brought him off a couple of minutes before (the end), because I thought he needed to feel that appreciation from the crowd for his performance.
"I thought he was magnificent, but I know what he's like. He'll be disappointed he came off with a minute or two minutes to go, because he wants to get that goal himself - that's the way he is.
"But it was good for our crowd to see that other side of him, that creativity side of him. Everything he did today came off."
