Yeah investing in the lower levels of referring is the simplest thing they could do, but your right, just shutting down any criticism. While I mightn’t support the teams, I admire Arteta and Klopp for speaking out about the poor levels of officiating, the league has been won and lost on a single point and even goal difference before, so every goal, foul, point can be crucial, if not a league then maybe Europe, or even relegation, it needs changing
