Totti’s career can be split into two parts, before ankle injury (1993-2005) and after injury (2006-2017). He clearly was never the same player after, he transitioned from a world class 10 into a good forward.
Totti circa 2000-2004 was as good as any other player on the planet. He carried Roma to a league title in 2001, and came within only 1 point of Juventus in 2002. Then he carried a relatively poor Roma side to another title challenge in 2004. This was around the time when Serie A was arguably the best league in the world.
The one big criticism of Totti was his inconsistent international career. He was great at Euro 2000, but flopped at the 2002 World Cup and 2004 Euros. Italy at the time was one of the best national teams on the planet, so he didn’t suffer the same disadvantage as he did when playing for Roma.
