I don’t even think this business is only for goalkeepers that they have so many in the team. Chelsea has the highest number of players for the next season and with that number, I am very sure it is for business because most of those players won’t even get to play any match with them throughout the season. What baffles me is that even as they have this so many players, they’re still looking to sign more to strengthen their squad. This looks like business because I’m sure they already have their main players for next season and the rest will just be for business sake.
The Community Shield is not a big competition but winning the opening match of the season gives the Man City players confidence and gives them a great spirit and will definitely get a good record this season.
Community Shield is also a trophy you can count to the many award trophies a club is suppose to have in their records room. None of the teams that will play in the community shield will not want to win the game or won’t take it that serious. Like you said, it will help build the morale of players to begin the season with. Every win is an encouragement and the first win is very important.
