I wernt the one that said they had to but I no who i'd rather have. In fact, it's part of the modern game that full backs do get forward get the odd few goals a season and provide assists. Evra Is good at getting forward for united and does provide assists but his finishing is pretty awful with the positions he gets into
playin a 4231 formation like we have for last few years its crucial mate thats what the 2 defensive midfielders are there for to cover when they do get forward. it helps having a full back who can actually defend, aurelio is decent at that and he's done a good job when rafa threw him on the wing occasionally too. insua can go forward but crumbles in defence, thats why we missed fabio imo
