""加上一隊球會比賽的贏輸吾系靠教練""

i dont think so.
managers have a huge impact on the team's performance.
players are individuals, they dont know what do to. at least they dont have the ability to clearly identify what the team needs.
simply like a company, the role of a manager is to guide/manage the individuals.
the better the management skill of a manager, the better performace a team would have.
a lot of ppl think that a football manager's job is to buy/sell players.
but wt a true manager does is to maximise the team's performance from what he has.
remember morinho in porto, moyes in everton, o'neil in aston villa.
their management skills really brought a huge impact on the teams.

of course, the wealth of the team, the luck involves in game also contribute to the result of the game.
however, 一隊球會比賽的贏輸does really affect by the performance of the 教練
