What is interesting, though – and encouraging for Arsenal – is listening to Klopp speak about his future. He is still only 47 and, while always stressing his commitment to Dortmund, he never makes any attempt to conceal a long-term interest in working in England. In the way that he has talked about the ownership of clubs with a history of managerial instability, it is also clear that he would greatly value Arsenal’s approach and history of supporting their manager both in good times and bad. Dortmund is a huge club – and it is clearly very much in his heart – but he must also look at the vast revenues that Arsenal bring in, as well as their wage bill, and wonder what he could achieve with greater spending power.
