Short summary / clarification

• I could not find a reliable match for a club named exactly “SLO. BRATISLAVA” that is documented as being coached by MARTIN RUSNAK in the 2020/21 timeframe.
• Two likely interpretations:
  • You mean the major Slovak club ŠK Slovan Bratislava (commonly shortened to Slovan Bratislava). For that top‑flight club, sources commonly list Ján Kozák Jr. as head coach around the 2020/21 season.
  • You mean a smaller/local Bratislava team, a reserve/youth side, or an amateur club that could be abbreviated as “SLO. BRATISLAVA” and might have been coached by Martin Rusnák; such lower‑profile assignments are not always well indexed in general databases.

If you meant ŠK Slovan Bratislava — general club profile (around 2020/21)

• Full name: ŠK Slovan Bratislava
• Country / City: Slovakia — Bratislava
• Stadium: Tehelné pole (Štadión Tehelné pole), Bratislava
• Club colours / nickname: Sky blue / white; often called “Belasí” (The Sky‑Blues)
• Competitions (typical for 2020/21): Fortuna Liga (Slovak top division), Slovak Cup, UEFA qualifying rounds (depending on prior season placement)
• Head coach (commonly listed for that period): Ján Kozák Jr. — if you specifically need confirmation for any match or date, I can fetch season match‑by‑match staff listings.
• Notes: Slovan Bratislava is Slovakia’s most historically successful club and participated regularly in domestic title races and UEFA qualifying rounds around 2020/21.

If you meant a different “SLO. BRATISLAVA” coached by Martin Rusnák

• Martin Rusnák may have coached at youth, reserve or lower‑division level in Slovakia; those postings are less consistently indexed in international databases. If you can provide the club’s full name or confirm whether it’s a reserve/youth team (for example “Slovan Bratislava B / U19 / local club”), I can prepare a targeted season dossier (squad, staff, fixtures, results and transfers) for 2020/21 where records exist.

What I can provide next (on confirmation)

• Full 2020/21 squad and staff list
• League and cup results, final standings
• Match list and lineups for the season (where recorded)
• Notable transfers and statistics

Please confirm whether you meant ŠK Slovan Bratislava (the top‑flight club) or a different Bratislava team coached by Martin Rusnák, and I will return a detailed season report in HTML format.
