Changing the formation that he is using without changing his playing tactics will not produce a good result he has bought good players but everything is looking like a joke still because the players aren't adapting to his performance if you look at the coach complain he's been blaming his players for the team's inability to win matches I think there is something that is going on in the team that is not known to the public and the formation is one of them because the coach is not used to the 4-3-3 but the formation seems to the one the players he has in his team is used to which could be what is making the team not to win matches. The coach should adjust to a new formation or get the right players that will match to his formation.
