plus he appears to have the wrong DOB listed here https://www.transfermarkt.co.uk/amir-ibragimov/profil/spieler/1065230 as the 2/4/2008 in your fmf its 4/4/2008
when combine your FMF with Data tweaks it shows two.
leaving this.
your version
their version
is there a way to have these merge if they had similar data or do I need to use one edit or the other ?
