This is like some illuminati sjw tactics of not being able to u read simple sentences.
None of the players you or I named....are bad. None. Not even Muntari. These are all actually good players. No, none of them is Messi or CR of their position, but they can still win european cups (yup, they both did) or play some good football (or be integral parts of the team). Every good team has their quality players in it, we are just so used of watching top tier teams that we don't appreciate the so called work horses like Lingard or Chivu.
There is lot of truth in what you said. It's on coach to bring the best out of players and for most part Jose is failing with few exceptions.
Players like Mkhitaryan, Pogba, Zlatan, Bailly, Lukaku were signed after having great seasons but for most part they are underwhelming.
Players like Rashford, Martial would walk into any squad in the league, they are very talented players and they even justified their position by scoring or assisting at superb rate, then Jose fucked it up by playing them as RW.
For all the shit Lingard gets, he saved Jose's ass on so many occasions. Fergie, Van Gaal, Jose all rated him and played him. Obvious whether the player is good or not when 3 of the greatest managers rates a player. Also Lingard has contributed nearly 20 goals and assists already with superb mins per G+A record. Scored 2 goals against Arsenal, winner against Chelsea, 2 goals against Burnley to make it 2-2 from 2-0 down, when Watford were all over us and score was 3-2, he dribbled from own half to score and make it 4-2.
He had superb season, not sure how anyone can even question his place in the squad.
Smalling was part of the defense with best or second best defensive record for last 2-3 seasons. Only players who played many games in that record is De Gea and Smalling.
Well to put in very simple terms, Jose is failing to get the best out of players. People here can go on and on about how Inter were warriors and Chelsea first stint players were all warriors, they all are missing simple point. Coaches peak and decline just like players. Some adapts, some don't. You can't go on and on about Inter 2010 forever. Since that happened, Inter warriors and Jose mastermind both didn't do much in CL.
