that's true and i don't particularly like the idea of spending so much on a lwb, especially considering alonso is probably too good to be a back up. however, wing backs are one of the most important positions on the field and help the team function. real madrid have been poor this season, and i read a stat which stated that many of the goals conceded have come from marcelo's side. if your wing back is having a poor game, it's more likely the team is going to concede. remember how poor we were a couple seasons ago with ivanovic on that right side? he got exploited constantly.
