Muttiah Muralitharan of Sri Lanka holds the record for most wickets in both Test cricket (800 wickets) and ODI cricket (534 wickets). His unique bowling action and exceptional control made him the highest wicket-taker in international cricket history. Wasim Akram, Anil Kumble, and Glenn McGrath are all legendary bowlers but none reached Muralitharan's tally of 800 Test wickets.
