Luis Enrique, Barcelona coach
My preference wouldn't only have been a couple of weeks to plan, but a holiday in the Maldives too! This is a bit similar to the PSG match but in theory we need to score fewer goals – instead of four, just three to square things. But I think Juve will have their chances, so our objective is to score five.
If we score the first goal early, the Camp Nou atmosphere will help conjure a second and third ... that'll take care of itself. Right now we've nothing to lose. There's only one option: attack, attack, attack. Then, when we relax a little, attack some more.
To the fans I'd say "don't leave in the 80th minute because you'll miss something, for sure." This is another night to make history.
Massimiliano Allegri, Juventus coach
We have to be clever in choosing when to attack, when to defend. I guess Barcelona haven't changed much in a week – they are full of potential, something we knew in Turin. We need to be smart. We need to be clear-minded, technical and not think of the scoreline. We will go out to try and win again.
Perhaps we'll adjust the tactics but I'd imagine they'll be very minor changes. Barcelona have three quality strikers but I'm confident that my midfield and defence can contain them.
Barcelona 3-2 Real Sociedad (Messi 17 37, Alcácer 44; Umtiti og 42, Xabi Prieto 45+1)
Lionel Messi moved onto 498 goals in all competitions for Barça during an eventful first half at Camp Nou. Deputising for Neymar, who was serving the first game of a three-match ban, Paco Alcácer marked his fourth Liga start of the campaign with a goal of his own after slick approach play by Messi.
Pescara 0-2 Juventus (Higuaín 22 43)
A much-changed Juve side opened up an eight-point advantage over second-placed Roma, who drew 1-1 with Atalanta, by defeating Serie A's bottom club. Gonzalo Higuaín's opener was his 200th goal in European league football. Compatriot Paulo Dybala was substituted early in the second half with an ankle injury.

Reporter's view: Graham Hunter (@BumperGraham)
Barcelona need to score three unanswered goals. No escaping that arithmetic, but there's much more in play here. Do they truly believe they can pull off a second footballing miracle in such a short space of time? And against much more battle-hardened footballers from the exceptionally streetwise environment of Serie A?
This group has throbbed with professional pride and competitive edge throughout their recent trophy-laden seasons and they themselves will demand a show of defiance in front of a passionate and hopeful Camp Nou. Will it be the high-risk 3-4-3? Can the MSN turn this around? It's unmissable drama.
