Cristiano Ronaldo has Luis Nani to blame for ruining one of his greatest ever goals.

It came in 2010 when Portugal took on Spain in an international friendly. Ronaldo sent Gerard Pique for an ice cream before lifting the ball over Iker Casillas.

We’d be talking about the goal today, it was that good. But then Nani happened.

The winger arrived at the back post to head the ball into the back of the net - even though it was a certain goal - and the referee ruled it out for offside.

Ronaldo’s reaction shows you just how annoyed he was.

Nani would go on to apologise to the four-time Ballon d’Or winner but one imagines Ronaldo has never fully forgiven him.

"I touched the ball because I thought I wasn't offside,” Nani was quoted as saying by The Guardian. “Everything happened so quickly.

"After having time to think about it I apologised to Ronaldo. It was a great piece of play and I shouldn't have ruined it."

Ronaldo's disallowed bicycle kick

It wasn’t the first time Ronaldo had an outstanding goal ruined. During qualification for the 2008 European Championship, the Portugal star had a bicycle kick removed from history after the referee deemed the ball hadn’t crossed the line.

The problem was that the ball had passed the white line.

Ronaldo’s stunning effort against Azerbaijan was resigned to the same fate as Frank Lampard’s beauty against Germany in 2010.

Both shots hit the crossbar, bounced over the line and then rebounded back towards the ‘keeper in a way that added some ambiguity to the referee’s decision.

And in both cases, the referee messed up. Check out Ronaldo’s strike below.

Ronaldo scored a brace

Yet we shouldn’t feel too sorry for Ronaldo. He had already given Portugal the lead and went on to score another as Luiz Felipe Scolari’s side cruised to a 3-0 victory.

Watch the Real Madrid star’s individual highlights from that match.

It would be another three years before Ronaldo would complete his move Real Madrid from Man United and we’ve witnessed a noticeable change in his play style.

Gone are the flicks and tricks, replaced by a clinical forward who simply overpowers everyone in his way.

One thing that's never changed, however, is his desire for goals.
