I think this comes up on a regular basis, and the question's a bit open ended as it could mean
a) do you like it in a sporting context?
b) do you like the constant speculation these days, exacerbated by social media?
The more elderly posters, ;), will remember the pre-window days where you could buy and sell until the end of March each season.
It could screw a decent season if someone came calling for a top player, equally it could provide potential salvation if you striker did his knee mid-October.
So
a) it's fair to all teams as you know you've got to work with the same squad for all but 1 month.
b) pretty fun watching some of the shit that flies around, so long as you don't get over invested (waits on the Wirtz signs for Bayern this window ;))
