Manchester United star Ronaldo has heralded the past season as 'spectacular' but warned his opponents he can still be even better.
The winger scored 42 goals in all competitions for United in a stunning campaign which yielded the Premier League crown and the Champions League title, and he has taken George Best's mantle as the most prolific midfielder in the club's history.
'Every season at Manchester United I have improved,' said Ronaldo.
'The season was spectacular and I scored many goals on the way to winning two important titles for the club.
'Next year I'm going to try and play even better and have an even better season than this one.
'I played a spectacular championship, a good Champions League and I am very happy with everything. It was my first European title and I want to win it many more times because the feeling is amazing.'
Speculation that the 23-year-old is poised to join Spanish giants Real Madrid has been rife all week but Ronaldo has reiterated his desire to remain at Old Trafford for the immediate future and insists he is now only focused on representing Portugal at Euro 2008 next month.
'I have a contract with Manchester United and at the moment I am only thinking about having a successful European Championship,' he said.
Ronaldo admitted feeling jaded after arriving in Portugal on Friday to join up with the national squad following prolonged celebrations in Moscow, but is looking forward to continuing his superb form on the international stage.
'I feel a little tired today (Friday) but I am going to have a rest in order to be ready for the Euros,' he told Portuguese newspaper O Jogo.
'I'm going to arrive there in form and anything is possible.'
