Are the ratings in brackets for the value Lyon got or whether the player was good? Because there's no way Umtiti for 25m was bad for Barcelona, he was world class for two years before he ruined his knee, Lovren was mostly trash but still a good deal for Soton because Liverpool bought him immediately for an inflated fee, Diakhaby had about one decent season before he turned to ****, losing Fekir for 20m to Betis was bad for Lyon but brilliant for Betis etcSince benzema in 2009 to Madrid their noticable transfers are:
2011 Pjanic to Roma for 11M (good)
2012 Lloris to Sp**s for 12M (good)
2013 Lovren to Southampton for 10M (good)
2015 N’Jie to Sp**s for 14M (bad)
2016 Umtiti to Barca for 25M (bad)
2017 Lacazette to Arsenal for 53M (mediocre)
2017 Tolisso to Bayern for 41M (bad)
2018 Diaz to Madrid for 21M (buyback)
2018 Geubels to Monaco for 20M (wtf)
2018 Diakhaby to Valencia for 15M (good)
2019 Ndombele to Sp**s for 60M (haha)
2019 Mendy to Madrid for 48M (good)
2019 Tousart to Hertha for 25M (bad)
2019 Fekir to Betis for 20M (mediocre)
2020 Traore to villa for 20M (bad)
Left 2021 and 2022 out because its too early to say but I have to say Andersen to crystal palace is looking very good.
Conclusion: the time where u could get value for money for players from Lyon has long past.
