Why would PSG sell Ibra? Especially for 15M? He has to force his way out.
Would he accept a big pay cut (probably more than 1/3 his current salary)? I'll believe it when I see it.
Also, once you start incorporating taxes, that difference increases. Zlatan is turning 32 in October, he would have no resale value, where as Jojo is 23, and well respected on the continent. It's a much more sustainable purchase; if things didn't work out, there would still be clubs interested in him.
