Clever from Timoney, he picks it up, pirouettes and all the Bordeaux players go outside, and he just has to fall over the line, they don't come any easier than that.

As good as Bordeaux are, they will give their opponents some opportunities. We saw that against Leicester last week, especially in the first half.
Ulster took that chance and must continue to show a clinical edge when given a glimpse inside French territory.

Ulster v Bordeaux (15:15 GMT)
Ulster hooker Rob Herring said he is "short of minutes" but is "feeling good" ahead of their second Champions Cup game against Bordeaux.
Herring made his first appearance for the province this season off the bench in their heavy 61-21 defeat by Toulouse on Sunday.
And Herring believes he is finally getting back to full fitness after a calf problem that saw him miss the start of the campaign.
"It was a frustrating pre-season for me, I got back close and then it was a re-injury, and it took a bit of time," he said.
"I'm feeling good, I've been training well, a little bit short of minutes but I'm trying to put in a better performance than last week."

Ulster v Bordeaux (15:15 GMT)
Bordeaux Begles fly-half Joey Carbery is looking forward to a "special" trip to Ulster in the Champions Cup on Saturday afternoon.
The 29-year-old former Leinster and Munster player will be taking on Irish opposition for the first time since he switched to the Top 14 side this summer and gets the nod in the 10 jersey after coming off the bench in last week's win over Leicester Tigers.
Having won 37 Ireland caps between 2016 and '22, Carbery has played with a number of those who will be in opposition at Kingspan Stadium, while he has plenty of experience of visiting Belfast with his previous employers.
"That rivalry is always there," Carbery said.
"It'll be interesting to see what it's like going over with UBB.
"It's very special for me to be going over with UBB to play in Ireland. I'll have family coming up to it, so I'm looking forward to it."
