Experts of last DAILY TOPIC:  What position would you choose If you could work in your favorite club?

@estera: Which position?? Hmmmm...maybe water girl ?? Uh ,what a demanding job , right? ?Well ,I will give my favourite players cold refreshment.,so it is pretty important !

For example: spotting potential signings that you think can fit in with what the club stand for and right now we are in need of one because Woodward is more of a business man to me and need guidance from someone who knows the game.

@Barcelona-Arsenal: I would really like to be the U23 coach for Arsenal or U18 for Barca because it would allow me to work with the future potentials out there

if not, i would really fancy being head Scout/analyzer, though it would be a hard job to get at Barca especially.
