The event, organised by the Brentford Community Sports Trust, saw the pair referee football matches in the sports hall before moving to the classroom for a Q&A session.
And the Bees duo found they had something in common with the students, who are preparing for their French oral, given their experience of learning English.
Barbet told getwestlondon : “It's funny to see people try to speak French but when they hear us speak English it's not perfect. We need to improve our English to understand everything said on the training pitch.”
Colin added: “Coming to the school brought back memories from my schooldays. It's nice to come and see people, especially if they're learning French.
“Sometimes, we know we don't understand the questions so I can understand when they don't know what we've said. To be a perfect student you need to start with the basics and build from that.”
The students were inspired by the two professional footballers and Head of French at the 1,900 strong co-ed school in Greenford Avenue, Mr Ben Bird was thrilled with the day.
He added: “The students loved it. It was amazing. It was a really good opportunity to see why learning languages is important and it can be exciting, fun and interesting.
“Bringing in the footballers has made them excited about learning French and it's not just a subject but also a lifestyle.”
Brentford CST Community Development Manager Luis Melville was equally delighted with how the event went.
He explained: “I think it's got to be right up there. The players really engaged in the whole process from when they got here and I think the students got a lot out of that.
“We pride ourselves on our work in the community and, with the foreign players here, it gives us another dimension.
“Events like this make it more real to students. We can expand them and take programmes into primary schools as well.”
