How Arsenal will Line up with Alexis Sanchez: Selection Dilemma

It looks almost certain that Alexis Sanchez will complete his medical and seal a deal with Arsenal football club.
The signing of the versatile Chilean international will be massive for the Gunners as top clubs like Juventus, Manchester United and Liverpool were eager to lure him as well.
However, Wenger still needs to add more quality in the squad to challenge for the title next season. A top striker should be the priority as Giroud is just okay and there is no depth as well.
Now, Sanchez has mainly played on the right wing for Barcelona and as a secondary striker for Chile but where will he fit in Arsenal.
Gunners already have so many playmakers with the likes of Podolski, Gnabry, Rosicky, Cazorla ,Ramsey, Chamberlain, Walcott and record signing Ozil in the squad. If all of them are fit, Wenger is going to have a huge selection dilemma and few big stars will have to start on the bench.
Playing Sanchez as a lone striker up front is a bad option because one, he is not an out and out striker, two, he is at his best in a free role.
Arsene Wenger has mainly used the 4-2-3-1 formation and with Ozil only at his best behind the striker and not out wide, Sanchez’ preferred position should be the right flank.
Here is how Arsenal will line up with Alexis Sanchez next season.
