Cristiano Ronaldo is planning showdown talks with his agent about his Manchester United future.

Ronaldo has become disillusioned with life back at Old Trafford and wants to meet Jorge Mendes to discuss what his options will be at the end of the season.

It is understood Ronaldo is hoping to have face-to-face talks with Mendes when he returns to Portugal in March for his national team's crunch World Cup qualifier with Turkey.

As exclusively revealed last month, Ronaldo is considering his future at United while he waits to discover who the next permanent manager will be.

But since then he has suffered a dramatic dip in form after struggling to form a positive relationship with interim boss Ralf Rangnick.
