4 – Olivier Giroud
The player has said that he’s decided to stay at Arsenal, but Arsene Wenger did admit that he left the door open for the Frenchman to leave this summer. A big late bid from Everton could change the situation entirely. Giroud has scored a lot of goals for Arsenal, including the winner in the Premier League opener vs. Leicester City, but he still very much remains the plan B at Arsenal and considering his age and the fact it is a World Cup year, the player would surely be tempted by the chance to become the main man in attack under Koeman at Everton. This looks to be the most unlikely of the four, but it would certainly be worth testing Arsenal’s resolve, especially if Alexis Sanchez does stay, as that further crowds the Gunners attack.
