The Reds visit Barça in the Champions League quarter-final second leg after losing the first leg 1-0 at Old Trafford. And while United were beating West Ham 2-1 in the Premier League, the Catalan giants followed up their win in Manchester with an unimpressive 0-0 away draw at La Liga's bottom club Huesca.
Ernesto Valverde's side are on track to retain their domestic league title but the seemingly inevitable crowning was slowed up by their hosts, who are rooted to the foot of the table in their first ever campaign in Spain's top flight.
Barça travelled to Estadio El Alcoraz without captain Lionel Messi who was being rested for the United game; also missing were Luis Suarez and and ex-United defender Gerard Pique, who were both serving bans, as well as Sergio Busquets, Sergi Roberto and Ivan Rakitic.
