Ronaldo's market value has decreased by 10 million to become 20 million euros in three months.

The main reason should be his not having much chance after starting to do his best to leave Manchester United. He hasn't played properly in the starting eleven for some time until the Europa League matches. I still don't expect him to be in the starting eleven in their next Premier League match. Actually his market value would still decrease slowly because of his age above all else. But his ineffective performance is helping his value to be lower quickly. Depending on his recent performance he has a less chance to find himself a club that is in the Champions League. So he needs to show a better performance to help Manchester United be a part of it next season.
