A lot of butt-hurt fans here it seems.
We can all agree that they are two different players and cannot really be compared.
Overall as a player Sanchez is the superior player. But as I stated before, he is an individualist. A selfish player but in a good way. His main asset is the ability to draw the opposition towards him freeing up the others within the team. He gets fouled a lot, so many dead ball opportunities are presented also. We saw this the other day when he claimed the penalty, you'll be seeing that a lot from him over the course of the season! The reason why he will work at United and be praised by many is those typical games you see where you guys look a little dull in attack. He can be and will be the catalyst to spark something which will lead to many goal scoring opportunities. This was especially useful to Arsenal, where he essentially produced moments of brilliance to secure some points for us or to further extend our lead to a comfortable non losing situation. However there will be many games where he frustrates, mainly due to the fact that his game changing techniques might not quite pull off.
However, he seems to be exactly the same kind of player he was at Arsenal. He wont adapt his playing style, so I highly doubt he will change or become a superior footballer over his time at United. You've got a ready made, PL adapted player. He will bark orders when the going gets tough and will often display his frustrations. Reading the match day thread I noticed many posts stating he was a class above the rest...I would say that's true. I think he is your top player at United (besides DDG) just as he was at Arsenal (although not this season). United are the bigger club, we all know that, but the truth is you are closer in quality to Arsenal than you are to Manchester City.
Furthermore I don't understand this BS argument about pressure. I would say that the pressure on Arsenal players is sky high. It may not be from the manager, who I admit takes it easier than most on his players..look at Cech STILL starting after that clanger... The fans have been restless for many seasons are not afraid to show their dismay when the going gets tough for Arsenal. For example Ozil has received plenty of flack from fans, opposition supporters and pundits for not turning up when the going gets tough. We don't see this kind of crucifixion on Pogba? We also have Arsenal Fan TV, a joke for many, which I admit, but the popularity of such channel and the fact that it often doesn't go ignored is another format of exerting pressure on players. You do realize AFTV has almost the same followers as Arsenal Official Youtube channel? lol...
Pressure is pressure, we are out of the champions league and it looks like we may be out this year too. Remember we have qualified for 20 years straight.
There is no difference in pressure for winning the league (which your team do not have as you wont win it this season) and competing for 4th or even getting a project done before the deadline at work. Arsenal fans arnt *****, we are spending a hell of a lot of money and expect to see a return.

Now onto Mkhitaryan, as I stated in another thread. He is the perfect Arsenal player. Folding under pressure relates to our defensive liabilities more and not necessarily the attacking/midfielding play. It's the defensive liability which you can't blame much on a player such as Mkhitaryan. However yesterdays performance he was the best player on the pitch easily. Ramsey scored 3 but Mkhitaryans overall play was sensational. Assisitng, tackling and tracking back to help out when needed. again it's early days but IF he carries on this form which we all know he is capable of, then we have one hell of a player on our hands. Essentially a better fit than Sanchez for overall team play.
He reminds me a little like Pires. He isn't naturally a winger but wanted to get involved so much with the play he that he just shifted his qualities out wide. 3 assists is a brilliant start. Attacking wise i'm not worried, but we still look shaky at the back. Mhkitaryan did try to contribute by tracking back and getting involved in all round play... Which is what we have to do in order to negate our defensive issues - defending as a team.
Another bonus with Arsenal, is that the responsibility no longer seems to be pinned on 2 players - Ozil or Sanchez. Ozil is our main creative outlet, with Sanchez being our main attacking outlet. This is no longer the case with Mkhitaryan and Aubameyang coming into the fold. Our "two main men" seems to no longer be an issue, we have other quality players now to spread the load. An overall positive for us.
Again it remains to be seen how well we will do with the remainder of the season, but truth be told we are in a better position now than before. The dark clouds circling over the club, with Sanchez staying/leaving, with Ozil Staying/Leaving .. eventual replacements, if any money will be spent etc etc have gone for now. This is a huge lift for the club and should correlate with better performances. Arsenal have the quality on paper, we all know it. Now we need to prove it and get as close to the top 4 as possible.
Sorry for long post.
