1. Will Xaxi depart on a high?

All good things must come to an end and so it is with Xavi and Barcelona. After an astonishing 25 years at the club he joined as a 10 year-old, the peerless midfielder will hope to bow out by claiming a fourth Champions League title and his 25th major honour overall. Chances are he will start the final from the substitutes bench as has been the case for most of the campaign but manager Luis Enrique will surely be moved to send him on for a late cameo, especially if Barcelona are winning the match. There have been rivers of tears all week from the player as one superstar after another lined up to pay tribute and it should be similarly emotional on the field come full-time before he departs for a new chapter in Qatar.

2. Is Andrea Pirlo on the move too?

There was an old Only an Excuse radio sketch in which "John Collins" talked about he and Paul McStay complemented each other in the Celtic midfield." Aye, I say nice things about him, and he says nice things about me." So it has been in the build-up to this final, with the tributes for Xaxi being matched only by the Spaniard's warm words for opposite number Andrea Pirlo, describing the 36 year-old as "the best in Italy". Pirlo has revealed he may consider a move to MLS in America should Juventus prevail in Berlin, adding that, after previously turning out for Brescia, Internazionale, Reggina and Milan, Juventus would be his last Italian club.

3. Can Juventus help restore Italian football's reputation?

Serie A has lost some of its lustre in recent times. Recent Champions League finals have been dominated by Spanish, German and English teams, with Inter - who won in 2010 - the only Italian side to reach the final in the previous seven years. Juventus' focus will be primarily on doing it for themselves as they contest their first final since 2003 and look to lift the trophy for the first time since 1996. But a victory over a strongly-fancied Barcelona side would also serve as a massive fillip for Italian football in general.

4. Will Lionel Messi further enhance his claim as the greatest ever?

The Argentinean already holds a welter of individual goalscoring records but could yet another attribute to that long list. A goal against Juventus would see him become the first player to score in three different Champions League finals after previously notching against Manchester United in 2009 and 2011. Messi's goal against Bayern Munich in the semi-final - when he embarrassed Jerome Boateng and left him floundering on his backside - is one of the highlights of this season's campaign. Many will be looking to Barcelona's number 10 to produce another memorable moment to light up the final.

5. Who will complete the treble?

Just as in 2010, both teams go into the final looking to complete a treble of European Cup and domestic double. Jose Mourinho's Inter side came out on top that year, defeating Bayern in the final to round off a remarkable year. Now Barcelona and Juventus find themselves in the same position, with both having already secured the championship and domestic cup. Inter remain the only Italian team to have achieved that feat, while Pep Guardiola's Barcelona are the only Spanish side to have done so the season before. Both Barcelona's Luis Enrique and Max Allegri of Juventus are in their first season in charge of their respective sides but already a place in history awaits one of them.
