MADRID (Reuters) - Not content with four titles in 2014, including his second Champions League, prolific Real Madrid forward Cristiano Ronaldo is determined to make next year an even bigger success.

Ronaldo netted 51 goals in 47 appearances last season, setting a record of 17 goals for one edition of Europe's elite club competition, as Real secured a record-extending 10th continental crown and the King's Cup.
