Long ball isn’t inneffective. One example is you still see Man City with Ederson launching it up to Haaland be very effective, and you still see the art of the long diagonal played by deep lying midfielders and CBs, as a Spurs fan, I remember Alderweireld being expert at picking out a Winger or Dele running between the lines. There’s only two types of pass, a good one and a bad one. Top teams don’t build their team around long ball because there is a certain amount of randomness and innacuracy with long passes which leads to a lack of control. There has been a significant effort in England for decades now to nurture technique and considering most Managers in the Prem are continental and will bring a continental philosophy and approach to how they play, rather than the old school long ball merchants of yesteryear.
