I understand what you're saying. Lots of physically strong youngsters fail due to lack of skills afterwards. But as I said, per se, him being strong is a positive. I honestly don't know what his career has been based on thus far.
That's not the general case. Saying that a player being physically strong is not a good thing is wrong. Per se, it's a positive. Each case ought to be approached individually. Might serve as a trend, nothing more.
Sarri's only success worth mentioning with Napoli (giving Juve a run for their money) was achieved by throwing all the other competitions under the bus. So yes, it's neat, but nothing spectacular to grant him the status he's got.
Have to disagree than Pep didn't improve their brand. Brought fresh style to the league, attracted lots of attention, played entertaining football. But result wise, should do better spendings considered.
