New Chelsea boss Andre Villas-Boas was preparing for a coaching career when he was just 14 years of age.
His teacher at posh Rosario College talks about his obsession with compiling reports on Porto - when he was aged just 14.
PE professor Jose Eiro said: "Andre was a friendly kid who had some good grades but didn't invest much in studying.
"What interested him was football. On Mondays he didn't just talk about matches, he brought a full report with tactics and substitutions."
