United's resilience and pressing allowed them to stay in the game for the full 90 minutes but Solskjaer's team were nowhere near as close to matching the La Liga outfit as the scoreline may have suggested. Given Manchester United's fine run of form under the Norwegian, prior to those two defeats, few were surprised at the decision but the run of indifferent form appears to have continued since he signed on the dotted line.
Solskjaer says Herrera is now out because of a "muscle injury" sustained in training but expects him to be available for matches against Manchester City and Chelsea at the end of April. Ernesto Valverde's men were far from their best, with Lionel Messi uncharacteristically quiet, though United failed to make the most of their periods of superiority and must win at Camp Nou if they are to progress any further in the competition.
He said: "They played better than us, it is fair to say, I don't think anyone will disagree".
Darmian has only started once since the turn of the year, while Rojo - seemingly always injured - has played just four times this season, his only Premier League start coming back in November against Arsenal. We do not want people like this associated with West Ham United. He's got another muscle injury.
"We got away with it, [it's] got three points".
United lost 1-0 at Old Trafford, putting us at a disadvantage for the second leg.
Pogba's future is likely to loom large over Solskjaer and United throughout the summer, as will the task of closing the gap to rivals Manchester City and Liverpool at the top of the Premier League table next season.
Last month monkey chants were aimed at England players during a Euro 2020 qualifier away to Montenegro, after which Tottenham defender Danny Rose said he was looking forward to retiring from a game which has done too little to tackle the problem.
They will end the day on 11th place, however, if they go on to lose the game.
