Inter Milan captain Javier Zanetti hailed their young matchwinner Luc Castaignos after victory over Siena.

The Dutch striker, 19, netted the first Serie A goal of his career following his summer move from Feyenoord.

"Luc is a very shy boy and reserved, but who's settling in very well to the group," the veteran told Inter Channel.

"We mustn't forget that he's a foreigner, he has to learn the language and get a feel for the place," he added.

"However, I think these young lads will contribute a lot because they are fitting in gradually and in spite of being forced to work under pressure, they were able to put their heads down and come out on top."
