SAINT-QUENTIN-en-YVELINES, France — What a magical week it’s been for Francesco Molinari and Tommy Fleetwood, who have been the stars of the show.

The duo became the first European partners to go 4-0 together in Ryder Cup history.

“I mean, what can you say?’’ European captain Thomas Bjorn said. “It’s a remarkable performance. That pairing came out of long conversations with the two of them and a relationship they built with each other over a long time. They wanted to do this, and when they kind of both said that they were really keen on that pairing, I started looking at facts and figures and everything that was built around them.

“Speaking to the stats guys and vice captains, there was never any red flags with the two of them, so I thought, ‘OK, we’ll give it a go.’ But from there, to do what they have done is pretty remarkable.’’

Phil Mickelson, who lost his Friday foursomes match paired with Bryson DeChambeau, was held out of both sessions Saturday, meaning when he plays singles Sunday he’ll have played only two matches in this, his 12th career Ryder Cup.

Some eyebrows were raised when Mickelson didn’t play in the Friday fourballs, because it suits his game more than the foursomes (alternate shot). But a source from inside the U.S. team room told The Post that Mickelson spoke to Furyk about not playing in the opening session because his form has not been good.

Mickelson, who was not made available for comment Saturday, was seen grinding on the practice range hours before he and DeChambeau were to play their foursomes match, so it seemed Mickelson was trying to find something in his game, which he apparently didn’t.

“Phil is a really good friend,’’ Furyk said. “We talked earlier this week about his play and how he was playing and his opportunities for play this week. He fully understood the role that he had [Saturday]. He said he would be ready [Sunday].’’

Asked if Mickelson was expecting to play only twice this week before the matches began, Furyk said, “That’s not the Phil Mickelson I know. He’s got a lot of confidence in himself. I probably didn’t envision him playing two matches, to be honest with you. I envisioned more, but that’s the way it worked out and that’s the way we thought we had to go.’’

The only other player who didn’t play Saturday was Europe’s Thorbjørn Olesen.

“I really wanted to get everybody on the golf course every day, but a couple of things turned out,’’ Bjorn said. “I probably really didn’t anticipate to having Francesco and Tommy on the golf course the way I did, but things happen and then you keep going with that. They were so keen, and they felt healthy, they felt fit. Then you end up in a situation where that was a really, really hard decision for me. [Olesen, who like Bjorn is Danish] is one of my dearest friends.

“Thorbjørn is a good egg and he’s a boy that will turn this around, and he might go out and show his old Danish friend that he was wrong tomorrow [in singles].’’
