Ole Gunnar Solskjaer defended Fred for the manner of Leicester City's first goal in Manchester United's FA Cup quarter-final defeat and said mistakes when playing out from the back will be "acceptable".
Fred received the ball from Harry Maguire on the edge of his own penalty area as United tried to build play, but his weak pass back to Dean Henderson allowed Kelechi Iheanacho to open the scoring in Leicester's 3-1 win.
United have looked to construct play from the back more often this season and Solskjaer believes they have made progress with it, despite the mistake at the King Power Stadium.
And the Norwegian has no plans to tell his team to abandon their principles of favouring clearing the lines after one error.
"We want them to build from the back. We've been really solid, we've been really good, we've built a foundation to play from with what we've done," Solskjaer told MUTV.
"Sometimes it goes wrong and that's acceptable. Everyone can make a mistake and we win together and lose together, as a team."
United equalised through Mason Greenwood in the first half, a well-constructed goal that involved contributions from Paul Pogba and Donny van de Beek, but goals from Youri Tielemans and another for Iheanacho condemned them to a first domestic defeat on the road in 30 games.
"Top goal, great to see Mason having that instinct again, a good finish. Good from Paul and Donny creates the goal without even touching it, it was clever, that's something to build on," Solskjaer said of United's equaliser.
