Both Juventus and Barcelona are looking to cap fantastic seasons by completing rare trebles when they meet in the Champions League final at the Olympic Stadium in Berlin on Saturday.

Juventus are appearing in their first Champions League final in 12 years as they look to win the European Cup for the third time, but Barcelona, inspired by Lionel Messi, are the favourites to win a fifth European Cup and fourth in the last decade.

Juve coach Massimiliano Allegri and his Barcelona counterpart Luis Enrique have already enjoyed excellent debut seasons in charge of their respective clubs, both winning domestic league and cup doubles, and both are now within touching distance of making it a glorious treble.

For Barcelona, it would be a second such treble following their fantastic first season under Pep Guardiola in 2008-09, but such an achievement is very rare indeed.

Only six other clubs have ever won a domestic league and cup double and the European Cup in the same season, with Celtic’s Lisbon Lions of1967 the first. Since then, Ajax (1972), PSV Eindhoven (1988), Manchester United (1999), Inter Milan (2010) and Bayern Munich (2013) have repeated the feat.

Barcelona can therefore become the first club to do it twice, and their current team contains several members of that 2009 vintage under Guardiola.

"We are still a young team. There are still quite a few players from the Guardiola era," said Luis Enrique. "This could turn out to be an historic season for us. "

Juventus, meanwhile, will either join that elite group of clubs or become the first club to have lost six European Cup finals.

The Italian champions' main task is to blunt Barcelona's razor-sharp attack of Messi, Neymar and Luis Suarez which has sliced through defences on the road to Berlin.

The South American trio have scored a stunning 120 goals between them this season, compared to the 103 managed by the entire Juventus team.

With 58 goals in all competitions, four-time world player of the year Messi is in the best form of his illustrious career, but Juventus can ill-afford to focus on containinghis talents alone.

Messi destroyed Guardiola's Bayern Munich with two goals in the first leg of their semifinal before setting up Neymar for the third at the Camp Nou.
