I saw it differently as it's become a game of cat and mouse now with the opposition very clearly knowing not to press Martinez and Onana. Instead, they are dropping off and baiting both of them to play passes into the middle spaces and pressing traps i.e when Casemiro/Eriksen have to receive a pass with a player over their shoulder.
I understand where you're coming from but I think it's a wise and smart move with how conservative and patient they are. Both Martinez and Onana were holding onto the ball and waiting for the Arsenal players to come onto them, then laid it off to Lindelof, who was the free man as a result of this. However, he barely played it to AWB, who had the space and instead kept pushing it back to Onana where we would just rinse repeat again. I think he was ill today so I'll give him a pass but it was disappointing.
