Ceferin may though have been here to get a handle on recent developments re City's ownership structure?
I doubt that a company whose reason for existence: profit, would invest in a football club who were about to sanctioned. If you suspected that they were, but still believed in the business case, you'd wait until after the sanction, and then buy the 10% equity for US$200m less. I suspect City have been is discussions with Silver Lake for ages, and the timing of the deal reflects City's confidence, and hence Silver Leaf's confidence that the impact of UEFA's investigation will be limited.
This maybe wishful thinking? Feels logical though.
