So near and yet so far for Wales, who saw a Six Nations Grand Slam slip from their grasp when France conjured up a magical finish in Paris to keep their tournament hopes alive.

Les Bleus looked dead and buried when they trailed 30-20 in the second half, only to produce a late, late show that means the identity of the 2021 champions remains unknown, at least for a few more days.

Perhaps it should not have come as a surprise that a crazy contest in the French capital ended in such astonishing fashion, though.

The two teams had played the game as if it was on fast forward in the opening quarter, sharing four tries during a frenetic first half that finished all-square, allowing all – playing and watching – to draw breath.

Wales, however, seized control after the break, Josh Adams' try – along with the boot of Dan Biggar – helping establish a double-digit lead. Another Six Nations sweep seemed a sure-fire certainty when Paul Willemse was sent off, the lock punished for making contact with an opponent's eyes.

The dismissal left France down to 13 at the time, prop Mohammed Haouas already sitting watching from the sidelines while spending 10 minutes in the sin bin.

Yet rather than accept the inevitable, the red card instead galvanised Les Bleus. As Wales became the team to lose their discipline, leading to yellow cards for Taulupe Faletau and Liam Williams, the hosts worked up a head of steam to come roaring back.

Charles Ollivon's converted try cut the gap to three and, on the final play with the clock having ticked beyond the 80th minute, France retained and recycled possession long enough to eventually create space out wide for Brice Dulin to dart over, in the process breaking Wales' hearts.

A championship devoid of fans due to the coronavirus pandemic had served up a visual treat for all those watching on from afar.

"I thought we were pretty good for 80 minutes, it was just those dying seconds," Wales captain Alun Wyn Jones told BBC Sport.

"Our ill-discipline probably brought a lot of pressure on. Credit to France for the way they played in the last 15 minutes, but when we look back at it, probably the ill-discipline brought all that pressure on, as well as good French play."

Wyn Jones knows what it is like to secure Grand Slam glory, having done so three times previously in his international career. Now he has experienced the disappointment of coming up just short. A game that was under control got out of hand, a situation that is never good to be in when France are the opponents.

The second-rower completed all 22 attempted tackles in the game, making him the first player with 20 or more in a Six Nations match this year with a 100 per cent success rate. He so nearly had the perfect outcome, too.

"We have been privileged to get on with the tournament and get a triple crown, but there was obviously more at stake today," he added.

They still may be crowned winners yet, with France – who scored four tries against Wales for the first time in the Six Nations – needing another bonus-point triumph in their rearranged game against Scotland to have a chance of leapfrogging into top spot.

Wales will watch on with great interest but, whatever the outcome at Murrayfield, they have come a long way in the campaign, one that followed on from a tough 2020 which included a six-Test losing streak, leaving coach Wayne Pivac under pressure.

Still, that will be little comfort in the immediate aftermath. A Grand Slam was seemingly theirs, only for Dulin to touch down and hand the Welsh with a result that will be tough to stomach.
