Mentioning van Persie and Falcao I mentioned the name of two low cost strikers who should improve our attack after the sign of a wonderkid/class young player like Julian Draxler.
Doesn't matter the past, Robin van Persie could be the perfect solution. His age isn't a problem because if Zlatan will be starter with United, I don't understand why our past captain not could be a first reserve having six years less than the sweden.
This is only a suggestion because we know what is our future in this transfer window. If Arsène will buy an offensive player (but he can choose to not buy anybody with the excuse of Iwobi and the new opportunities for Chamberlain and Walcott), will not sign a second striker.
Imagine you a 4-2-3-1 with Xhaka and Ramsey on midfield, Sanchez on the right, Draxler on the left and Giroud on attack with Ozil behind him. When the frenchman will sleep for 15 consecutive games like last season, instead of Campbell or Walcott, we will have an outstanding alternative...and I'm sure, if a player like van Persie will accept to challenge with Giroud for a shirt into the starting XI, after three o four games he will beat him to be the number 9. I know, it's impossible because the armony into the group would unbalance because the return of a former captain, with number ten, with the record of goals scored in the recent years and an open letter before to join the rival, isn't simple. It's hard to admit it, but we need Robin (or a player like him) because I don't see strikers better than him on the market. If you don't want to buy him, you're costricted to break the bank and pay normal players like Lacazette and Morata.
