Wenger is a world class manager, he does a remarkable job with the money he has available to him. If Arsenal lost him they'd drop down into mid table very quickly
This is the same Arsene Wenger who before the foreign billionaires ruined the top flight, beat SAF to the title on 3 occasions with similar if not worse resources. His side even went unbeaten for a full season. I know he hasn't won a trophy in years, but what chance does he have with ££££ and £helsea spending millions each season, on transfer fees and wages. Even we have far more money than Arsenal, we don't spend as much as the other 2 but we do spend a fair bit, to compete with them. I am convinced that if football was on a fairer playing field like when it was when AW first joined Arsenal, AW would have won a few more titles. Even now he is doing a fantastic job with limited resources, I doubt there are many other managers who could have kept Arsenal in the top 4. Look at Liverpool they spend far more than Arsenal yet Arsenal are a far better side. If AW was to leave Arsenal, he would be in high demand across Europe. Real Madrid have been after him for years
