Captain Robert Lambert will spearhead a patched-up Great Britain side's hopes of reaching the World Under-21 Team Cup final.

The King's Lynn Stars heat leader will ride at number one for his country in this evening's semi-final in Denmark. And much will rest on the British Under-21 runner-up's performance if GB are to progress with fellow high-profile team-mates Adam Ellis and Josh Bates, who beat Lambert to land his homeland's major youth crown earlier this season, being forced to withdraw through injury.

Lambert – who also competes for Premier League Newcastle – will now line-up alongside Zach Wajknecht (Somerset/Birmingham), Jack Smith (Birmingham) and Max Clegg (Wolverhampton/Edinburgh/Cradley).

Britain will come up against Denmark, Australia and Norway in the meeting. The winners will progress to August's final in Sweden – where the hosts already lay in wait.

The best-scoring second-placed team from both semis will also progress.
