I think you are misconstruing my term for laziness as I do not limit it to a physical application. I said it's his approach to training, and one does not need to be "more professional" than the baseline to simply turn up on time for example. Repeatedly taking a piss shows a lackadaisical approach.
Sure no one used the term "lazy". They just pointed to his attitude in podcasts unimpressing team mates, and then teammates himself saying he needs more professionalism. You can insinuate from that what you will but combine that with how he likes to turn up late repeatedly for training, I dont think its a far jump to conclude the approach is a laid back or "lazy" one.
My overarching point being, this is just one of many reasons we should avoid such a player. The other more important ones being, he doesnt want to come here and can't seem to stay fit.
