I'm right. The most minutes that he has played with the stats you shared is the equivalent of 20 games, it's the season with 8 goals and 12 assists in the league. The other seasons it's less than 17 games.
In fact I generally underestimate his stats, they are actually excellent for someone that doesn't rely on that at all and for which lack of end product is a fair criticism when you see the amount of chances he creates with ease. I get that people like to hate on players but Coman is someone that doesn't deserve it, he plays Football the right way and has a great attitude on the pitch.
