To me loyalty's a commodity in football.
Raised in South America, football & loyalty go hand in hand. When Beckham left for Real Madrid is was seen as an aberration, same with Figo.
I tend to stay with the very first club I arrived at. There's nothing greater than creating a winning franchise, a dynasty.
Unless I receive an offer I can't refuse (after winning it all with Tottenham and having announced a link with Barca, a year later they offered me the gig when Guardiola left), my loyalty's true to my first team, even though I try to get the most from the boardroom, of course. If they're not open to getting feeder teams, improving junior coaching, youth recruitment networks, expand stadiums, after I've given them every trophy out there, then I place my ultimatum.
