ROME (AP) Cristiano Ronaldo's future at Manchester United became uncertain again when he wouldn't say whether he will remain with the English champions next season.

When asked after United's 2-0 loss to Barcelona in the Champions League final whether he would be at Old Trafford next season, the reigning world player of the year said: "I don't know."

Real Madrid has been trying to obtain the 24-year-old Portuguese winger for nearly two seasons and former president Florentino Perez is on the verge of heading the club again.
