Yes, because it all starts with the manager. Messi didn't pick the 23 man squad, nor the lineup, nor the tactics. Sampaoli does. Messi wasn't involved in the 6-1 and 4-2 beatings from Spain and Nigeria. THe problems go deeper than Messi, and it starts with the manager. It is up to the manager to put his players in the best possible chance to succeed. Finally today, he goes with a 4-3-3, gets Messi out wide to free him up, and starts Banega and benches rid of Willy. This manager has been making a ton of questionable decisions, and the primary blame goes to the manager. United fans of all people should realize that a poor manager can handicap a team with poor tactics. We know first hand the difference SAF can make, compared to a Moyes. Managers matter.
