Name: Arisvaldo Pereira

Nationality: Brazil

Club Mentioned: K.R.C. Genk (Belgium)

Notes:

• I could not find records of a widely known Brazilian player named "Arisvaldo Pereira" who played for K.R.C. Genk in major historical databases, transfer records, or common public sources up to my knowledge cutoff.
• Possible explanations:
  • The player may have been part of Genk at youth, reserve or trial level and thus not appear in first-team databases.
  • The name might be spelled differently (e.g., Arisvaldo vs. Arisvaldo, Pereira vs. Peixera/Pereyra) or the player may be better known by a nickname, which is common for Brazilian players.
  • The player's tenure could be very brief or at amateur/semi-professional level, limiting public records.
• If you can provide additional details (approximate years at Genk, position, age or date of birth, common nickname, or previous/next clubs), I can attempt a more specific search or match alternative name spellings.
