The Portuguese star sparked controversy after claiming he felt ‘betrayed’ by United, while revealing he does not respect manager Erik ten Hag.
The 37-year-old also took aim at the club’s owners, the Glazer family, Gary Neville, former team-mate Wayne Rooney and ex-interim boss Ralf Rangnick in the wide-ranging interview.
United are now considering sacking Ronaldo for a potential breach of contract as a result of the sit-down with Morgan, and Ten Hag has reportedly told club bosses the Portuguese forward should never play for the club again.
While Ronaldo is being heavily criticised for the interview, his sister has launched an impassioned defence of her brother on social media.
In a lengthy post on Instagram, Katia insisted her brother had nothing to prove and could
‘scratch your balls’ for the remainder of his career and still have ‘built a legacy for the next generations that nobody can take away from you’.
‘I’m glad your character and dignity don’t leave you,’ Aveiro wrote.
‘I feel sorry for people who live with their chins up pointing fingers as if they had built more than you.
‘There are people who are like this: weak, untrue (I don’t even know if this word exists) but I’m not at all worried about it.
‘Nowadays seeing someone take a stand, being brave, being safe is criticised, people drown in their own illusion, many of them live to see others walk, even the floor itself is afraid to step, because they are afraid of falling, poor things.
‘Nowadays it’s hard to find people like that, you had everything to keep silent. You don’t need to prove anything anymore, you built an empire from nothing, you already have a legacy for the next generations that nobody can take away from you.
‘You could scratch your balls (yes I say it anyway ) and whistle to the side, ride your private jet wherever you want, you could take a ride in your 27-metre long boat and enjoy the days in the sun in the country you want.’
Aveiro went on to praise Ronaldo’s achievements and for ‘never deviating’ from his path during his successful career.
‘Everything you have (conquered with a lot of sweat) is a lot and it’s yours alone…’ she added.
‘You could and you can do anything you want, but once again you decide to be different and brave as few cowards are, to be an example of a man is to fight without fear of stains that easily disappear from the horizon, to be a man is not to give up on your ideals, to be a man is to show the truth is to face the sharks and keep swimming, (your children will be so proud of you), your end has not yet arrived, but these last years are exactly the same as the beginning… remember?
‘Where they said, he’s not going to get anywhere, he’s not going to be anything in life, he speaks wrong, he’s weak, family of fragile and aimless people.
‘They only those who know where they came from, know where they are going, and you my brother know well what you are made of. Congratulations on never deviating from your path, it was always you, and it will always be just you .
‘No problem. You can handle it, you are unique, you are special. I’m so proud. Thanks bro.
