He has Good arguments but based on false premised:
1. Premise 1: Mourinho has no patience to improve what he has:
Rojo, Valencia, Young have all gone up a level defensively. Darmian returned to form last season, though he is off the boil again. Jones is fit again and one of the best defenders in the league after years of injury woe and mockery. Rashford is now an effective presence on the wing, which he wasn't before. Martial is now excellent defensively and no longer runs into cul de sacs. Fellaini has got even more effective under Mourinho. Herrera had his best season last year since leaving Bilbao, in spite of his current strange loss of form . Lingard is now
one of United's key players. Mhikitatryan had a night mare start to his United career, yet Mourinho patiently nursed him into one of United's top performers in their Europa campaign last season and looks like he has to redo the trick. He has waited patiently for Shaw to return to fitness. Rather than doing a Guardiola and replacing his fullbacks. Matic who is the toast of the town was told 'good riddance, "you're past it' by his own fans in the summer.
Verdict: False
2. City are good this season because Guardiola has developed players:
Were Fernandinho, Otamendo, Stones, De Bryune, David Silva, Bernardo Silva, Mendy, Walker, Gabriel Jesus, Ederson, Sterling and Sane all class before Pep signed them? Yes
Are they still class? Yes
Did Sterling show this form in his first season at Liverpool ? Yes
Isn't he replicating it because of maturity due to age in a performing team? Yes
Wasn't Otamendi once voted LA liga defender of the year? Yes. Was it down to Pep? No. Isn't he showing that form again? Yes.
Verdict : False
3. Pep has patience to improve what he has:
Tell that to Jesus Navas, Gael Clichy, Mangala, Bravo, Nitcham, Iheanacho, Nolito and Fernando. Delph survived due to being injured in the summer.
Verdict: False
4. United fans wouldn't have swapped Sterling for Rashford:
Yes. Just not for the reasons Carragher is arguing. Rashford is seen as a future CF and symbol of United's local grown talent. Sterling is just a super English talent like one Wayne Rooney. Fans love the earlier ones more always.
Verdict: true but misleading
5. "If you want to evolve a club you don't call Mourinho'
Chelsea and Abramovich say hi. Mourinho left foundations that won the champions league years after he left. He built the bulk of the Real squad that has now conquered Europe 3times. Even back to back.
Verdict False
6. Mourinho doesn't use the raw material he has. Only loves ready made talent:
Porto, Chelsea and Inter. 3 times he built teams on either young players or cobbling existing resources together with new ones. Besides, like Guardiola he HAS earned the right to only coach clubs that spend heavily on top talent
Verdict: false
