Sean Lamont will be reunited with his brother Rory at Glasgow Warriors next season after agreeing a three-year deal to return to the club where both started their professional careers.

The signing of the 30-year-old international winger is the latest evidence of new ambition at the very top of the Scottish game to generate real competitiveness within the country's professional teams.

It was little more than a fortnight ago that Rory was sufficiently persuaded by what is happening at Glasgow to agree to take a drop in salary to rejoin his old club. He registered a crucial first try since his return during Saturday's drawn Heineken Cup tie in Montpellier.

In some ways, Sean's decision is more significant since, unlike his younger brother who had fallen out of favour at Toulon, he is still clearly central to what is happening at the Scarlets who are going well in both the Heineken Cup and the Rabodirect Pro12.

The pair are particularly close. Indeed, Rory's career began when Sean persuaded Sean Lineen, the Glasgow Warriors head coach who was then the club's backs coach, that he had a brother who was at least as good as he was.

Both clearly enjoyed working with Lineen and this time it seems it has worked the other way with Rory's presence at the club helping persuade his older brother that the time was right to return. I've heard all about the plans to keep developing Glasgow on and off the field, and can't wait to have a look around Scotstoun Stadium, where we'll be playing our games as of next year," Sean said yesterday.

"The club have clearly come a long way since I was last involved and I'm thrilled at the prospect of playing my part in helping them write the next few chapters in the story.

"It will also be fantastic to be back at the same club as Rory. We both took huge pride in wearing that Glasgow jersey a few years ago, and it will be something really special to be pulling it on together once again."

It was clear that the older Lamont, who left Glasgow to join Northampton Saints in 2005 before moving to Llanelli in 2009, had not faced an easy decision.

"I'm pleased to have my future sorted out in such a positive fashion, but for now it's about putting the move to one side and giving my all for Scarlets during the rest of the campaign," he said.

"I've thoroughly enjoyed playing for the club. They've been great to me and my family and I am very grateful for the opportunities I've been given. It's been an excellent time for me and one of the best moves of my career to join such a positive and energetic team environment and the chance to play a brand of rugby I thrive on and enjoy.

"I would like to express my sincere thanks to Nigel Davies and the coaching team at the Scarlets. The opportunities I've had in the Scarlets shirt for the past three seasons have re-ignited my enjoyment and spirit for rugby and have no doubt enhanced and promoted my international career.

"This was genuinely a very difficult decision for me and having spoken to Andy Robinson at Scotland, it's probably the right move for me now and it gives me the chance to take my young family back home which is important to me personally."

For Lineen, too, this clearly goes much deeper than merely signing a high class player, albeit he appreciates that as his squad improves so the expectation and pressure builds.

"I'm massively excited to have brought Sean back on board. He's a real tough competitor who knows his way round the RaboDirect PRO12 and Heineken Cup, and offers great positional versatility to boot," he said.

"He's always kept Glasgow close to his heart, and that passion will be a fantastic asset for us when allied to his obvious playing and try-scoring ability.

"With David Lemi and Rory Lamont also having joined, we've now signed three fine international players in the last month. It's a real statement of intent from the club and Scottish Rugby and it's now up to us as a squad and coaching staff to make the most of the tools we're being given."

The man providing them with that support is Mark Dodson, the Scottish Rugby Union's chief executive who is very much putting the organisation's money where his moth is in terms of the promises made when he took on the post.

"This is another very encouraging piece of news for the Warriors and Scottish Rugby in general," Dodson said yesterday.

"Sean is an important part of the national team set-up who will be a real asset for Glasgow going forward.

"The Warriors have performed well so far this season, and we're delighted to support their efforts to keep improving." for the opportunities I've been given.
