Jamie Heaslip has tasted Six Nations title, Grand Slam and Heineken Cup glory this season - but he admits being part of a British and Irish Lions tour is "living the dream".

The Ireland number eight lines up against the Sharks on Wednesday night, looking to underline what most pundits believe - that he will secure a Lions Test place in the opening appointment with South Africa on June 20.

"This tour is bringing the best out of everyone," said the 25-year-old Leinster star.

"It's living the dream right now - the atmosphere is great."

Heaslip though, insists his thoughts are not on the three-Test series at this stage of proceedings.

"There are three more games before the first Test match," he added.

"All I am worried about is Wednesday night and getting out there and doing a job. Your biggest game is the next game."

Heaslip's back-row combination with Tom Croft and David Wallace has Test team material stamped all over it, as does the centre pairing of Brian O'Driscoll and Jamie Roberts.

But Lions head coach Ian McGeechan has revealed he is unlikely to give his Test team a trial run before the first Springboks clash.

"The main thing had been to get everyone playing in those first three games. Now, in the the next three games it is to keep looking at some of the combinations," said McGeechan.
