I think i'll go with Pep's analysis of the problem rather than yours & Delph's, if that's alright, he seems to know what he's doing.
I would too, my point being to say it refectled on him poorly is a bit ott wouldn’t you say? His job isn’t tactics and analysis. As a player involved in watching team mates not follow runs and concede goals you can see his frustrations in saying “we stopped running” he may be right, he may be wrong, reflected poorly? Do me a favour
