You basically need a new board, new coach and clean house properly. Its difficult and will take years. Lack of long term vision from the board is killing us currently.
I am not a fan of the current board but I don’t know what vision Font has in the sporting realm so I question if a new board will make any significant difference.
We definitely need new players (to replace the old guards). I don’t want to sound ungrateful but we will sure hit a rock bottom when Messi, Suarez, Pique, Busquets etc. are out but we should start getting better from there, with new players and a cultural change, one that focuses on work rate, hard work and making tireless runs than some sort of eye-trickery and nice moves.
I hope by then we will get Nagelsmann for a complete rebuild.
