Now in the source where I look at them they are as follows:
4.80 - 3.95 - 1.71
In fact, I am surprised because even 1.61 I considered generosity on the part of the bookmakers. I don't know what this is connected with (there is nothing in the news about one of the leading PSG players being poisoned or something like that), but usually such a sharp move on the part of bookmakers means that either they know something or fans are making a disproportionately large number of bets on the underdog.
Money is still flowing for PSG, it was 1.67 a minute ago, got a refresh and

But the biggest spread I see is for X, from 3.6 to 4.1 wonder what people think it might happen, a draw till the 90' and then PSG winning in overtime?
I see double chance x2 at 1.2 and 1/2 at 1.12 so more inclined for a draw rather than a straight win even from Chelsea backers?
