Canada-born de Guzman has eight caps for his adopted country Holland and played a minor role in their near-perfect World Cup qualifying campaign, making two starts and an appearance from the bench.
But with attacking midfielders of the calibre of Wesley Sneijder, Arjen Robben and Rafael Van der Vaart regular fixtures in Louis van Gaal's selections, it could prove tricky for the 26-year-old to force his way into the reckoning for Brazil.
Monk declared the Villarreal loanee man of the match at the Liberty Stadium, and said the versatile player, who has recently moved from central to a wide position, was the kind the Swans should sign on a permanent deal if they can.
"He was our best player today," Monk said
"He typified everything that I asked of the team for this week - not just on the ball, but off the ball.
"The two goals that he got were special and very good finishes and he showed another string to his bow - that he can be asked to play in other positions.
"I think if he continues to play like that he'll give himself a very good chance of getting in the World Cup squad."
Monk said goalkeeper Michel Vorm often talks of the culture in the Dutch squad when he returns from international duty.
"They talk about how the competition in that squad's so high, the ruthlessness of the manager and what he wants, what he demands," he added.
"It's going to be hard, but you (De Guzman) keep putting in performances like that and you'll be giving yourself a very good shout."
If De Guzman does figure prominently in the Dutch World Cup campaign his value could soar, something interim boss Monk is well aware of.
After the win over Norwich, he added: "I think after performances like that it's something for the club to think about, but obviously that's a conversation I have to have with the chairman, the player's agent and the player himself.
"At the end of the day, the player has to want to be here
I'm sure that conversation will happen very soon."
