I would simply replace him with someone who can see things like: Busquets and Rakitić can't play together anymore for example.
and how do you know which coaches will bench old guard players??
all coaches look like genius at small club where they have full authority, no pressure and can try crazy tactics even if it drops points.....
at barca legend players ex: busi,raki,alba,pique,suarez,messi have much more status and power than the coach and must play due to board pressure, marketing reason and high wages.
also new players are shiny toys and overrated too much, while old players get abuse even if we win league every year.
pressure to win at barca is a immense one. any coach except maybe 2-3 in the world will come here play a standard 4-3-3 with all legend players. no matter what they did at previous clubs, barca is at different level and they cannot afford to do revolutions. by that time they will be sacked already. we played 4-3-3 for years, give valverde a credit for going with a pragmatic 4-4-2 when we had no wingers and only lost 1 match.
do you think a sarri or a tuchel would come here and do some big miracle? no, they would play 4-3-3 with mostly same players valverde is using and the matches will still be boring.
valverde is best man for the job at the moment imo.......
