The sister of Cristiano Ronaldo is urging him to leave Manchester United - online.

Ronaldo's fairytale return to Old Trafford has not gone as hoped, with the club failing to qualify for next season's Champions League.

Though his individual numbers remain impressive, he has cut a frustrated figure at times during what will finish as the club's worst ever Premier League campaign in terms of points on the board.

And in response to a fan post suggesting that Ronaldo should leave the club to boost his chances of winning trophies in the final years of his career, his sister, Katia Aveiro, appeared to support the idea by liking the post.

The Instagram post by Portuguese fan account @cr7.o_lendario, wrote: "It's very sad to see Cristiano Ronaldo in this situation with this Manchester United team. Now we are without a place in the Champions League.

"Cristiano does not have to stand [stay] as proof of love for the club, the greatest proof of that was he returned to Manchester United having also had a proposal from Manchester City with clearly a much superior squad, coach and by recent history.

"Cristiano has to think about Cristiano now. Manchester United will still last another thousand years. Cristiano, you have four more, five years of your career. Look for a better team now because you deserve it and because you still have a lot of football [trophies] to win."

Aveiro, a Portuguese singer with 1.2 million followers on Instagram, suggested she supports the now deleted post by liking it.
