Ribery or Fabregas

In player transfer market, Barcelona is too slow. Their rival - Real Madrid had signed Kaka, Ronaldo, Benzema and Raul Albiol for their new squad. These new players will certainly give Barcelona a lot of trouble when they met. Actually, Barcelona is aiming for Cecs Fabregas from Arsenal dan Frank Ribery from Bayern Muenchen. Which one is the most important? Both of them are, but if i have to choose, i pick Ribery instead of Fabregas, Barcelona need something to cover left field, Thiery Henry is good, but he sometimes spend much time recovering from injuries. Ribery had the speed that every football club needed. His 'killing' insting sometime helps when he score. Offense and Defense both exist in Ribery. Fabregas? i don't said that he is bad, but Barcelona already had some players that could cover the mid field. Arsenal has gave Fabregas permission to talk to other club, but i still don't agree if Barca choose him over Ribery.
