I think that, at some level, early goal concession is a symptom of the same problem of mindset. Bournemouth & Newcastle are just two recent examples I picked, but there are countless other instances of the same problem dating back to the first few games of the season and, indeed, several times last year (Sevilla at home, most prominently). I agree that there's a difference between being placed on the back foot with a goal conceded in the first ten minutes compared to an away game vs Chelsea, but if the team's overall philosophy is always to contain and only attack with maximal caution, you invite the risk of lapses in concentration much more easily. As I said in a previous post, I am actually not wholly against a philosophy of being solid first and then hitting a team on the counter (as Inter often did under Mourinho), but the problem is that even while containing (let alone breaking forward), there is a complete lack of intensity. As it was brutally exposed against Bournemouth, this lack of intensity -- from the very outset -- can be catastrophic, and our only saving grace in that game was that they were unable to capitalise on their dominance and go two, three goals ahead. You rely quite heavily on luck (and a world class goalkeeper) playing a game of containment with a lack of intensity, and my worry is that luck will not always be so kind to us.
Having Herrera as a more regular component of our midfield helps mitigate against this as he is one player who constantly plays at a higher tempo off the ball. But, of course, this is seldom accomplished by one player, and requires a more holistic team approach to be effective.
