I really don't think it's that simple. I agree 100% with you that they seem unprofessional out there, but they could be running their lungs out and trying their hardest and still look unprofessionally bad, because individuals can't be organised by themselves, and a defence most definitely can't.
I know people call 'Shola' 'stroller' because of his lazy style for example, but none of our players are being purposefully s*** I don't think, or nonchalant, they just don't know what the f*** to do because they haven't been coached well enough.
None of them are standing hands on hips, they're just being pulverised by a slick, robust and well-drilled unit that know what they're doing, and know how to pull apart a collection of individuals.
They might be running a lot but mentally they aren't there. Probably just can't wait to get home like most of us feel like when we are at work.
