I think the lack of panic is the mental side but also a reassurance in their ability. They know they are all great at football and given the system they play it's just a matter of time untill they get chances on goal. We haven't got the same quality so it's understandable why the players panic when it's going wrong. We are building towards having that level of technique throughout the squad but yes it's going to take time. It does mean at some point replacing Johnson with someone who does have good technique in tight spaces and congested areas, someone who can beat his man with a move or swivel rather than just a knock and run and it won't be just Johnson the whole first 11 will eventually be evolved to play this way. That's why a signing like Bergvall is so key imo, yes he's young but he already has those key attributes, he already has the touch the control etc. Now it's about building his tactical profile to fit and grow in our system.
Yes that kind of player is difficult to find but they do exist. At the moment the obvious candidates are Ederson who really looks the part to me, Zubimendi, Fabian Ruiz and annoyingly the new Arsenal guy Merino. I imagine Gray is our long term solution so we possibly already have an our guy, just one who will eventually take over from Bissouma.
