Put to Solskjaer that Pogba's statistics have tailed off dramatically, the United boss said: "I think he has made a difference for us in a few games, so has Romelu (Lukaku), so has Marcus (Rashford)".
"We've had Antonio (Valencia), he's going; we've had Ashley (Young); we've had Paul (Pogba), we've had David (de Gea); Chris (Smalling) has been captain, so there are players here who can be captain on the pitch".
"There will be a couple of changes". "But we've let him focus on his fitness".
While planning to shuffle his pack once more, Solskjaer has a number of players unavailable to him. "He's very positive, always helping and always giving advice". He trained individually yesterday.
"We don't have full-backs this week".
United are in sixth place in the Premier League, three points outside the top four, having lost four out of five matches in all competitions since their remarkable victory over PSG in Paris to reach the Champions League quarter-finals.
Barcelona are famed for their ball retention and United face playing much of the game without the ball.
