He already has made it. He's on a great contract at one of the biggest clubs in the country. He's got about £20 million left to pick up in wages over the next three years; all he has to do is show up. If he retires at 30 he can live the rest of his life in luxury.
As long as we don't sign a replacement we might as well keep him. He's always been overrated on here but he's better than he showed last season. He should start 16/17 with fresh legs too after having the summer off which might be worth something. One key point about Wenger to keep in mind is that he has never in his entire life built a team that doesn't expose struggling players terribly. Whoever tears a ligament or does an ankle is in for a rough ride. They will not only be picked week in and out after they've recovered; they'll be played out of position in unclear roles where their weaknesses are enhanced.
