Gerard Pique says Barcelona will have achieved a perfect season if they beat Juventus in Saturday's Champions League final, and thus match the feats of Pep Guardiola's 2009 treble-winning side.

Barca's current boss Luis Enrique can finish his first season at the Camp Nou by emulating Guardiola's feat of steering the Catalans to the treble of Champions League, La Liga and Spanish Cup on his debut year in 2009.

With the Spanish league and cup already in the bag, Barcelona can write history by seeing off Italian champions Juventus at Berlin's Olympic Stadium to become the first team to complete the treble twice.

"It's going to be a great season whatever happens, if we win this Champions League final, we'll be writing history. It'll be the perfect season, like in 2009," said the Spain international.

"To have two titles and to reach the Champions League (final) is something we would have enjoyed anyway, but we have this one last chance to win and we're 90 minutes from perfection."

The 28-year-old Pique was part of Guardiola's squad which won 14 trophies from 2008-2012 and he wants the current star-studded Barcelona to prove they are just as good as the 2009 model.

"The main thing here is we are again in the Champions League final," said Pique.

"I hate comparisons. I hate it when we weren't winning last year or two years ago and we were being compared to Pep's team.

"I don't want to be compared now. It's a different team, but there will be people who think we play better (now) or who prefer how we played a few years ago.

"The main thing is that it's working, we need to focus on this game, if we play like we have all season, we have a good chance to win."
