Really? Personally, I find blues to be useful when playing against equally strong or stronger opponents. Further, if I let morale drops to poor, I see the morale of more players dropping as well the following day. Maybe it's just confirmation bias on my part, but my first eleven are always on 'Very Good' morale, at the minimum.
As Niko said, don't exhaust your free vids. Otherwise, the 2X training option won't be there.
