What they've lacked for ages has always been better goalies, better full-backs and CBs - even midfielders to a certain extent.
They've always been stacked up front.
I do like what's Scaloni's been doing though - calling up young and hungry players with Messi being the glue.
In 3 year's time, there's a chance they will put up a proper fight for 2022. Next summer Messi should aim to win the Copa America as well - they're looking to be the best South American side at the moment, and their new generation is only getting started.
