ive stopped reading your post after the part i bolded out, because i thought you were gonna repeat what you said before again, but now i see you added a few more points this time...
1st, the team didnt "suddenly" start working when Marchisio was back, we didnt look all that good for the 1st 2-3 games despite the wins. why was that? because its not all on Marchisio missing (and now you are giving credit to Khedira too finally, which is great, but those 2 werent the only things we were missing), which you are implying here. here is why we actually were looking bad. we started the season without 3 key players from the previous year, we signed 10 new ones, 4 of which (2 were direct Marchisio replacements, because of which we played Padoin as regista in the 1st 2 games, and 2 were our offensive wingback pair) were very late into the mercato and without having any preseason with the team. was that all? ofcourse not. due to so much new players incoming and some leaving, IN ADDITION to injuries of very important players like Barzagli, Lichtsteiner, Pereyra, Asamoah, Khedira, Marchisio, Morata, Mandzukic at different points during the opening months of the season, which forced Allegri to change between 3-4 different formations, all led to a very poor start. Pogba (and the rest of the team), who struggled with form since he got the injury vs Dortmund and continued his bad form into the new season, couldnt carry a team like that. in form Pogba couldnt even do it probably, because we had no clue how or what we are supposed to play, new players (especially those who arrived late) needed time and Allegri needed time to find the ideal system. once all that happened, once Allegri sticked to the 352, once injured players returned, once AS, Cuadrado and the rest settled in, once Pogba found form again, once Dybala got to start regularly, only that is when the team really started playing well.
we agree that Marchisio and Khedira were important (obviously), but if you are gonna put our comeback solely or mostly on them, then youre wrong, as ive explained it for the 2nd time now. about the games Pogba played without Marchisio and/or Khedira, why do you think i mentioned that example to you? 1st ill say that it wasnt Khedira who made Hernanes look good vs Bayern (lol). Hernanes played better in the 1st leg actually, and we used a Pogba-Hernanes-Sturaro midfield in the 2nd half. the whole team looked better than with Marchisio and Khedira in that game. we also had no problem kicking Citys ass with Hernanes-Sturaro and Pogba had no problem creating most of our attacks and providing the 1-1 assist.
"How many games did Pogba shine with both Khedira and Marchisio out?" - the sample size of the games, as well as the timing when those happened, cant be used to determine if he can or cannot carry a midfield. you are taking a period at the beginning of the season when Pogba was out of form, we looked clueless as a whole and had so many changes in the team so we needed time to get settled, and are creating your opinion about Pogbas ability to carry a midfield/team, and you go all peasant with your "oh look, Marchisio and Khedira come back and we play well again, lol money dab ho cant play without WC midfielders babysitting him", while you ignore all these other factors i mentioned above. how many games did he play without Khedira and Marchisio before/after that and how many good ones did he have, thats the question you should ask yourself. its too bad youre banned now but feel free to respond whenever you return
oh and about me being a United fan now, i wasnt the one watching their game and commenting on it the other day

just another thing, for the record. i expect Pogba to have a slow start at ManU mostly because he will be joining them without preseason and as i expect will be used in a 2 man midfield with Carrick at 1st, before Mourinho settles for a different system eventually. since i expect you to make the mistake and preach how you were right after 4-5 games (we all know you wont be able to resist, again), im asking you to not do it but wait a little longer, because eventually you will be proven wrong (again). just a friendly advice
