If Raul Sanllehi stays true to his word, we won't allow a player to enter the last 12 months of his contract ever again. That means this will be Aubameyang's last season at the club unless he sign an extension in the next few months.
What makes the situation trickier is that we won't have the money to replace him without Champions League football. If we sell him, we're unlikely to get more than £30m. Lacazette won't be the answer because he is in the same situation. It looks like we'll have to sell both our strikers, which may give us £80m at best. We need to spend most of that money in other players, however.
Even though it will hurt us a lot, we'll have to sell Aubameyang to the highest bidder. At least we can start rebuilding the team sooner than later.
