The 33 year-old is famous for not making it in the pros as a player, but is remembered fondly at junior club Ramaldense FC.
Porto fans are fuming over Villas-Boas' departure - but Ramaldense members still remember him fondly.
Nelson Carvalho, one of the club directors, told The Sun: "Other big names in football have passed through. But we are very proud of Villas-Boas because he didn't forget - he mentioned Ramaldense when interviewed on television.
"He will always be invited back as long as that remains the same."
What made him noticeable was his ginger hair, which led to the Little Carrot tag.
Agostinho Marques, a seven-a-side junior coach at Ramaldense, revealed: "The Little Carrot was a fun nickname, not nasty.
"He was a nice boy and we all think about what his time in London will be like.
"His life here is very soft compared to what he will expect in the Premier League. Here, he deals with the Press very calmly - it may be different now."
