If John Terry left Chelsea I'd definitely support wherever he goes.
Imho this is stupid question.. You cant support a team because of a player, you may like/follow it... For example, if Pandev goes to Villareal, i will watch them, and would like to be succesfull, but wont support them, Inter is my team, and atletico from la liga...
so if you support barca because of messi, you dont really support barca, you just follow them because of messi and want to do good to please your favourite player...
i stayed here when yaya left..
The hammer blows of first Santi Ezquerro then the Ogg monster leaving almost pushed me away from Barca, but I got through it.
No player is bigger than the club.
