The duo turned up at Newcastle School for Boys, in Gosforth, where Gutierrez pitched in with a Spanish class and Marveaux helped out some pupils who were learning French.
They were asked a range of questions in their languages including who the joker of the Magpies' dressing room is, just how good is Demba Ba, what do the players get up to in their spare time, and whether they like the cold English winters.
And the players were more than happy to lend a hand.
"It is good that we can come here and help people learn a foreign language," said Gutierrez.
"Knowing how to speak another language is very important. When I came to Newcastle I knew a bit of English because I started learning it in school in Argentina at the age of seven, and that made it easier for me in this country. Hopefully we can help these pupils improve their language skills so that if they go abroad they are able to use it."
Marveaux added: "I was very impressed with the childrens' French-speaking ability. They asked me a lot of different questions, including some funny ones about me and my teammates.
"Their questions were good, they had clearly put a lot of effort into them and they are learning well."
