I'd be all for this if it didn't further dent the odds of "smaller" clubs winning titles or nicking CL spots, i.e. Atletico or Dortmund being raided in March before the run-in to a domestic title or CL final.
What I don't understand, is how the window shuts on slightly different dates in different countries, public holiday depending. Surely the window needs to shut on the same day for all clubs in Europe. It seems obvious that English club officials are working and negotiating right through the bank holiday using it as an extra day.
Think the window should start before the season begins, can really damage a side when one of the bigger clubs come in and steal away one of smaller teams key players, so that they can`t find a replacement or alter the strategy.
