It reads to me like this:
Came out post match and gave the media the blunt talking Ronald routine...the man who pulls no punches, yada yada yada. Then he later thinks that it's a better idea to make sure the progress he's made with the team thus far is to the fore instead: so the positives of last week are highlighted more and the initial 'searing criticism' is counter productive to that.
Koeman is no different to all managers - they frame everything as evidence that they are in complete control and the plan is working.
But he said it wasnt working, he said some of the players didnt press, he also implied that some players will be dropped.
