Both the team players and coach all have to be be identified as unique contributors that determines what the team achievement is, we also have to go furthermore looking into the internal conditions with some of these teams and see how things are going on beyond all we only see online through their performance during their matches, a lot are going under from the decision making process and this also have something to do with how the team players or coach performs.
Even team's win or lose is unique and the cause to such win or lose is always tied to one indices or the other which is mostly analyzed by the sports analysts. However based on experience, people often tied the win or lose of clubs to the head coach for not being able to other use the right formation or for benching a player or the other plus other tactical errors identified.
Unless if a particular player misses an obvious opportunity available to him to score, until then the blame still lies on the neck of the coach. People often neglect the management for not making the right investments, forgetting these coaches have limited capacity to perform unless being properly supported by the management.
