His current market value is about €180m, it is lower than the price was in 2018-2019 when the price reached €200m. Mbappe gets difficulty to show his best form this season, it is decreasing a bit. It makes sense if his market value is decreasing to €180m.
Don't think so, his current market value is way lower, probably not over 100 mil.
He will be a free agent in 6 months.
