Its "broken" in that its still a bit lacking in balance no matter the lineup. We have like 5 or 6 players who probably offer nothing other then extra bodies. Plenty of average players on huge wages. Some players who are always injured. Others who don't try hard enough. Sometimes if we get the best balanced team in terms of quality and work rate, its not big enough for Mourinho or strong enough. If we go for more strength, we sacrifice on quality.
De gea, valencia, bailly, carrick, herrera, pogba, Mata, martial, rashford and Ibra I think are the only players who should be untouchable really. We know they are quality when on form, there aren't or shouldnt be doubts about their potential with what they can achieve here. Of course Ibra and Carrick are old while Martial and rashford are very young, but that group really should survive and changeover (unless the old guys retire or whatever). Possibly Shaw in there, if he gets his confidence and form back to pre leg break. Mkhitaryan if he ever wins Mourinho over would go in the above group too since he can be a world class player for us. The rest are all dispensible players who either lack in ability, or effort, or potential to get better. So thats what, 10-12 players who are definitely good enough and have shown that quality and/or potential in the past 12-18 months? Sure some of the others like Smalling can be good squad players, but he'll always make us lopsided in terms of passing the ball out from the back when he plays, or Blind who is quality on the ball but then lacks in physicality and might not be Mous ideal type. You can probably say smalling and Blind would be really good squad players. but that still leaves around 10 players who dont really serve much of a purpose and are significant downgrades over the starting option (or are always injured), and most hate when they see in the starting 11 (darmian, jones, rojo, schneiderlin, fellaini, schweinsteiger, memphis, lingard, young, rooney). Not sure if I'm missing someone.
But with Mourinho seemingly not being a fan of Smalling, Shaw and Mkhitaryan, and bailly and valencia picking up decently big injuries, while carrick is too old to play every game, martial has struggled at the start of the season, rashford being a kid still and Ibra went through a rough patch, is it any surprise we've been struggling a bit? Only pogba, mata, herrera and de gea basically are players that can be relied upon to play every game and haven't had injuries.
