E: 05/06 Win a football signed by Leo Messi

Link isn't working?

I could be wrong but I think you have to be a registered 'Barca Fan' to be included.

The rules are very long but this bit

"f) The emails must correspond to registered “Barça Fans”. Otherwise, the reserves shall be contacted. The following will be asked
for checking purposes: (i) name, (ii) surname(s), (iii) nationality and, if applicable, (iv) member status. "

I hope that helps

"CONDITION 4. PARTICIPATION PROCESS.
All those interested in taking part in the participation process, regardless of their status as members of the CLUB, must fulfil the
requirements given below:
a) Have the status of “Barça Fan” and maintain it for at least until the date of the draw, scheduled for 6 june 2017.
b) Have an email address which is “registered” in FC BARCELONA’s "Barça Fans" database.
c) Register as a “Barça Fan” on messi500.fcbarcelona.com/, providing the data required for such purpose: (i) name, (ii)
surname(s), (iii) country (iv) postcode, (v) email address, (vi) date of birth.
d) Each “Barça Fan” participant can take part once (1) and will therefore only register once (1). Any duplication will be monitored
by a computer security system to ensure that only one (1) registration is admitted per participant, all additional registrations by the
same person shall be terminated.
e) One (1) single file will be created from a correct “registration of participation” as has been stated in this condition, regardless of
the language used. "

I think I have answered my own question - you become a Barca Fan when you submit the entry form... I have left up though in case anyone else is unsure
