England flanker Magnus Lund will be joined at Biarritz next season by his brother Erik after the 6ft 8ins Leeds lock agreed to sign for the Basques.

The transfer, which had been mooted for months now, was finally confirmed ahead of Leeds' final league match of the season, and after they had secured their Guinness Premiership status.

Erik - nicknamed 'The Viking' - admitted it had been a tough decision to leave Leeds for the Basque outfit, but admitted that the family connection had been the clincher in his move.

"There are some obvious reasons why I decided to join Biarritz, notably the chance to play alongside my brother, to play in the Heineken Cup and experience a new lifestyle," said Lund.

"All of those were beyond Leeds Carnegie's control. However, it was incredibly difficult because of how special this group of players are here.

"We have developed a great team spirit, and that is all about us working together. It was an uneasy decision for me to decide to leave that behind," he added.

The Norwegian international has agreed a two-year deal with Biarritz and said he felt he was leaving Leeds "in a strong position" after they secured the Premiership status. "I have got a lot of friends here at Leeds and I will always have a strong link to the team," he added.

Fellow Heineken Cup finalists Stade Toulousain have also strengthened their squad for next season, with the signing of Dax's Argentine scrum-half Nicolas Vergallo.

The 26-year-old, who has seven Test caps for the Pumas, has primarily been signed as cover for Frédéric Michalak, who will be out until the new year following a serious knee injury.

Vergallo has agreed a one-year deal with a further option for another year, but will behind both Byron Kelleher and Jean-Baptiste Elissalde (in addition to Michalak) in the Toulouse pecking order.

Heineken Cup organizers ERC, meanwhile, have announced that the Stade Toulousain-Biarritz final will be shown live and in 3D in selected French cinemas.

"This is an extremely exciting advance and development for our tournament and will bring our prestigious 15th tournament final to an even wider audience," said ERC chief executive Derek McGrath.

"It is entirely appropriate that the first Heineken Cup match to be shown in 3D in cinemas should be the final and we look forward to the tournament successfully crossing this new technological frontier," he added.

Another rumoured transfer could see France prop Sylvain Marconnet, 34, depart Stade Francais for Bayonne. According to Canal+ the deal could be concluded next week, with Marconnet's departure a reflection of the current financial difficulties being experienced by Stade Francais.

The Basque club has been busy in the transfer market since it escaped relegation to ProD2 - due to Montauban's bankruptcy - and they have been further linked with a move for South African Joe Pietersen.

The 25-year-old Stormers player can fill a variety of roles in the backline - from full-back to winger - and has previously represented South Africa at sevens level. Bayonne are also being linked with Australian flanker Cameron Treloar, who is currently playing for Italian side Prato.
