Ok I have the following suggestions if you can fix:
1. The inbox with the messages from the team should be on the left sidebar because no one is interested to read first the messages from other teams.
2. When you Add Club you should bring back the sort by option within the GW and team view because is not working right now.
3. Player changes option is a mess, in the old version you had the option to view which was their team, and also to sort out players based on their changes, saying this from all the players we put on shortlist, and I think that you can add this small piece into the mix by showing the number +/-1 that was the change, their team, and the option to sort players, because the cosmetic changes with their photos are not necessary.
4. Basically sorting is a must within the SQUAD tab
5. Club - Transfers just bring the sorting here too
6. View Match was a much better option when it popped out when you logged into your club because you could view the report right away. I would also suggest to have the old option of View Match Report when you want to view the results because making more than 2 clicks is annoying for visitors *talking from a developer point of view.
This is my insight up until now, if you have decided to roll out this new design to all managers I though to bring my opinion so you could make these minor changes for the managers.
All the best JM
