When I was an English teacher in Porto (many years ago), me and another English teaching friend rang up FC Porto and asked if we could bring our football-mad teenage students to meet Bobby Robson, who was then managing the club. Obviously we fully expected a no, but to our surprise, the club put us through to his office and he picked up and agreed right off the bat. We got to see a closed training session in the Antas Stadium itself (the old one), and then we went down to the offices and he sat and chatted and answered all of their questions for close to an hour, before taking us on a tour of the trophy room. He just seemed genuinely happy to offer whatever he could to us.
A smashing bloke and a real gentleman. RIP
