It's barely contribution tbh. It's fake news and wasted bandwidth. PSG haven't spent anything this summer and was very, very moderate in last 2 summer transfers for the club of their financial strength so there is absolutely fuck all anyone should investigate about them and their money spending.
I'll repeat my contribution again if you need more time to understand it:
PSG's 2015/16 transfer window - 79.22 mil. GBP net loss, 2016/17 - 72.08 GBP net loss, 2017/18 so far +850k net profit. COmbined - around 150 mil. net loss.
City's 2015/16 transfer window - 124.02 mil GBP net loss, 2016/17 - - 151 GBP net loss, 2017/18 so far - 172 mil. net loss (with Mendy included and with the lowest reported fees for the likes of walker and silva). Combined - around 420 mil net loss.
So, PSG could spend 270 mil. more in this transfer window to get to the level of our net spend in last three or 170 mil to the level of our this summer spending, so your so called contribution is pretty much only bitterness and unfortunately the raggishness the portion of our fans are showing these days. I'm fairly sure lot of City fans would be very happy to support some new FFP now we've survived the first one and that makes them same level of dicks like those arsenal, liverpool, bayern, rags and other isstry fans who were moaning and screaming when we broke their status.
