They are the type of numbers that seem inconceivable at first glance. Then you remember we are talking about one of the greatest players in the history of the game.

By the time the World Cup comes around in two months, Cristiano Ronaldo will be on the cusp of 200 caps for his beloved Portugal — not to mention more than 100 goals. When it comes to representing his country, there is no question of his importance to the side, even though he is less than five months out from turning 38.

While all is rosy on the international front, the superstar has been in the headlines for the wrong type of reasons. Namely, the summer-long saga involving his future at Manchester United.

The whole episode did not cover him in any glory and understandably a portion of United fans are keen for him to be shipped off in January if possible. Many wanted him gone as soon as it was made aware he wished to leave in the summer. Whatever the reasons behind it, it didn't happen and he's stayed put.

That is not to say he cannot play his part this season and, who knows, maybe even further beyond that.

Erik ten Hag has so far been content to use Ronaldo sporadically, with just one league start since he walked in the door (albeit there was the caveat of him missing pre-season due to a personal issue).

But given the fixture congestion that lies ahead, the Dutchman will surely be banking on being able to call upon Ronaldo on a more consistent basis as the season goes on. At 37, he does not have the luxury of being able to wait around months. He needs game time to build fitness for the World Cup, and if that means Europa League matches or Nations League assignments for his country then so be it.

Some have questioned his commitment to the cause but you only have to look at his stance when it comes to Portugal duty. Ronaldo rarely, if ever, shirks call-ups and a measure of his desire to continue playing at the highest level was evident with his latest comments. He was asked whether the upcoming World Cup in Qatar was likely to be his swansong with his country and his answer was unequivocally clear.

Cristiano Ronaldo has started just one league game so far under Erik ten Hag this season.

"It has been a long road, but I would like to say that my road is not over yet. (You're going to have to) take a little more road from me," said Ronaldo.

"I hope to be part of the federation (team) for a few more years. I still feel motivated; my ambition is high. I'm in a team with young people. I want to be part of this World Cup and the European too; I'm going to assume that right away."

His longevity, in terms of consistently performing at the highest levels in the sport, may never be witnessed again.

While he may not be the player United had first time around, or even the one we saw last year, you should never rule him out. The fire is clearly still burning deep within.
