Because.... he speaks Portuguese? A little tenuous imo...
It's a wider cultural thing than just language, but yes, language is important. Links between Portuguese and Brazilian football are very strong and Brazilian footballers move to Portugal as their first stop in Europe more than any other country. They are very homely and patriotic the Brazilians, and anything that makes a place feel more like home they respond to.
So yes, language, wider cultural links, AVB's knowledge of Brazilian football...all that stuff would indeed appeal to Brazilians and perhaps be the difference between a young Brazilian choosing Spurs over Porto or the likes of Seville or Roma or whatnot.
