Loic Remy:
The one transfer which is arguably the most important for Arsenal is that of Loic Remy. While Alexis Sanchez can play in the position of a striker, his best position at the moment is on the wings and he would have to be moulded into a striker by Arsene Wenger. Olivier Giroud is the only option that Arsenal has upfront and the Frenchman can help Olivier Giroud greatly in sharing the burden upfront. Loic Remy is a class talent who can bang in the goals for fun and with the services around him, he should fare really well at the North London club. He would not be very costly for a player as talented as him and Arsenal should not have any hesitation in snapping him up.
Signing Remy could mean that Arsenal can go back to their counter attacking football, which were so dominant during the days of Henry and Pires. With the pace that Walcott, Sanchez, Ozil and Remy have, they could form a devastating partnership upfront.
