Most appearances in European Championship
Aside from becoming the European Championship's most prolific goal scorer with 9 goals, Cristiano Ronaldo also holds the record for being the player with the most appearances at the Euros and even become his country's all-time most capped player and the first player to play in three Euro semi-finals.
The previous record for most appearances at the Euro was jointly held by former France defender Lilian Thuram and legendary Netherlands goalkeeper Edwin van der Sar who both played 16 games at the Euros. By virtue of playing in the final group game against Hungary, Ronaldo held the record with 17 games.
By the end of the tournament, that number went up to 21 as he broke records aplenty on his way to his first international tournament victory. Seeing as no player has played more than 16 games or three semi-finals, it looks as though this record might yet remain for a while longer.
Aside from equalling the record for most goals in Euro history, Ronaldo also created a slew of other records as well. He became the first player to score in four different editions of the European Championship (2004, 2008, 2012, 2016) and has more Euro goals than any other Portuguese player, beating Nuno Gomes' record of 6 goals.
