2. Charlie Austin
It might be a bit of a longshot but QPR will get relegated unless a miracle happens and Charlie Austin would probably move to another Premier League club at the end of the season. The 29 year old has been the star player for QPR in a season which can be forgotten, he has scored 16 goals already this season for a struggling club.
He probably would not start every game for Arsenal and would play second fiddle to Giroud but he would be an amazing option to have on the bench, especially since he has hit the high notes in the Premier League and is ready to make a switch to a bigger club.
