Kazan: Cristiano Ronaldo brushed off speculation about his Real Madrid future, although Portugal conceded a late equaliser in a 2-2 draw with Mexico at the Confederations Cup on Sunday.

Ronaldo, 32, is reportedly furious over a tax probe into the off-shore accounts dealing with his image rights, and has reportedly vowed to leave Spain.
According to Spanish paper Marca on Sunday, Real Madrid's coach Zinedine Zidane even broke off his holiday to call Ronaldo to try to persuade his star not to quit the club.
But Portugal's talisman was at his best in an action-packed first half in his team's opening match, with hosts Russia and New Zealand still to come in the group.
