Wales prop Samson Lee says he's finally back to full fitness after a near year-long recovery from a ruptured Achilles.
The 23-year-old was hurt in last season's Six Nations against Ireland but has now played in his country's last four games.
That includes World Cup encounters against Australia and South Africa and he will be involved against France on Friday in Cardiff.
Scrummaging cornerstone Lee concedes his comeback has been testing but he believes he is close to his peak once again.
He said: "The Achilles feels back to normal and I have been working a lot on strengthening the calf. It feels a lot better.
"I knew it was going to be tough to get back after such a serious injury, but I kept on working hard in rehab and now I feel back to normal.
"When you snap your Achilles, obviously you are going to lose bulk and strength in your calf. I lost about two to three inches off my calf and I found I was using my right leg more than my left.
"It was a big operation and there is a big old scar there. It was one of my big worries how I would be able to get the strength back but it was all about rehab, rehab, rehab."
Wales' scrum has proved a potent weapon during this season's Six Nations, with Lee's Scarlets colleague Rob Evans commanding rave reviews for his displays on the loosehead side.
His success has not surprised Lee after they teamed up at the 2012 Junior World Championship in South Africa.
"We have played together for a long time now," Lee added. "Rob is pretty confident in himself and you just let him crack on. He has done well.
"We played against each other for the first time at under-16s, then we played together for west Wales, the districts and then came through the academy together at the Scarlets. We are quite good mates."
"After the way we have performed in the opening couple of weeks, I can't see why we can't put in another big performance against the French.
"You play against French packs - whether it is at international or club level - and they are always big heavy packs.
"It will be one of the toughest scrums we will come up against during the Six Nations. It will be a big challenge for us this week.
"We have also got to have plenty of confidence in what we have done in the opening two rounds and take it into this week's game."
