I feel it's pretty obvious about Alves. He's only 27. He can give us another good 2-3 years of service. Perhaps even up to 5. Why spend money in the transfer market while we already have one of the best RB's in the game today? Plus there's no youth player shining in that position. I say we save the transfer money, another few years trying to adapt another RB into our system, and just keep Alves. His teamwork with Messi, alone the rest of the team, is just perfect. We don't need to mess with that.
Also, if Alves stays another 3 years or more, it'll give us time to develop a RB from our youth system. Wouldn't that be nice?
