From Cavani.. to Higuain... then RVP... to Suarez.. then Dzeko as RvP back-up.. then to Jovetic.. back to Suarez.. then back Dzeko.. to Llorente.. to Negredo (I don't think Juve is interested in Negredo - only AS has reported this, and AS is known to report nonsense time to time).
Arsenal are very into Llorente. They've been linked all summer, and their previous foward buys don't affect anything. Wenger is aiming for a 3-prong attack and needs a top-class CF, and he's been known to favor Llorente for that position. If Marotta wanted Llorente, he should have struck a deal before the RvP sale. But he waits... waits for the price to go down... never happens.
Llorente would favor a move to Arsenal over Juve. Mult. reasons: Offer competitive salary and UCL football; relatively new, top-class stadium; most watched football league world-wide; link-up with fellow Spain internationals; and, no coach/scandal issues. This decision will be massive for him as he eyes WC2014, particularly after not being used at Euros. He wants to prove his worth.
