The financial aspect has become the dominant factor in the transfers of players, not the sporting aspect, and most of that the big stars who enter the last year of their contracts without renewal.
Perhaps the most prominent model at the moment is French striker Kylian Mbappe, who is on the cusp of leaving to Real Madrid from Paris Saint-Germain in a free deal.
That would rattle PSG I must say when or IF he leaves. He has always dreamed of playing for Real Madrid.
