Correct. Also if some players would pull their fingers out of their asses, looking mostly at you martial, DeGea and lindelof
Manager is responsible for form of players. And manager's job is to pick a player, bench a player, train a player and make him better than he is. Also his job is to motivate players and his job is choosing best tactics, formation and style for team which he has.
IF it is only one player (Martial) i would agree with you maybe. But except Bruno and Shaw; who is having really good season?
Greenwood is not a shadow of player from last year.
Rashford is playing one good game and 3 bad.
McT has good run lately because of goals scored but his season in overall is average at best.
Maguire and AWb are part of defence which is doing silly mistakes all season.
Telles was average.
VdB having a mare of season
Fred plays hot and cold.
"Future superstar" Tuanzebe looks like championship player.
So to sum up; Bruno and Shaw are great, Pogba, Cavani and Rashford had some good runs in form. And that is it. So surely it is about manager, not players?
