What do you value most? Highest peak, consistency at high level, how he was considered in the season/at the time or the performances in the national team? Ronaldinho had a higher peak and since the end of 2003, early 2004 was already considered by the Spanish media (Mundo Deportivo) as the best player in the world - even before being elected - and that was until 2006. After the failure of Brazil in the WC his hype went down and between injuries and a controversial photo showing Ronaldinho out of shape at the beginning of 2007 his high-level almost ended (some glimpses in 09/10 with Milan). Xavi, on the other side, had a arguably smaller peak (he was never really considered the best in the world) but both in clubs and in the national team he had a period of high level maybe between 2004 and 2011/2012 or at least 2004 and 2008 -2011. Highest Peak: Ronaldinho Consistency: Xavi How was considered at the time: Ronaldinho National Team Performance: Xavi In general... I feel OK if you put Xavi above Ronaldinho.
