The Red Devils ended the 2018-19 season on a disappointing note following a surprise 2-0 loss to the relegated side in front of their home supporters at Old Trafford.
Manchester United finished in sixth place in the Premier League table and five points adrift of fourth-placed Tottenham Hotspur.
Solskjaer initially made a brilliant start to his interim reign as manager after the Norwegian head coach was appointed as Jose Mourinho’s replacement back in December.
However, Manchester United endured a turbulent final couple of months following a run of two victories in their last 12 games in all competitions.
Solskjaer will be hoping to rebuild the Manchester United team in the summer months ahead of a top-four challenge next term.
Speaking at his post-match media conference at Old Trafford following their humiliating 2-0 loss to Cardiff, Solskjaer said:
“The boys need a break, because they worked extremely hard to give us a chance to challenge for the top four which was nearly impossible around Christmas time.
“Then we had a bad, bad period towards the end.”
He added: “They’re good players you know, but they’ve hit a brick wall more or less towards the end and we’ll get them positive again, optimistic again.
“Today, we created an unbelievable amount of chances, we just couldn’t score, and that’s human nature.
“When you’re not confident, feeling the world’s against you, those margins will go against you.”
Manchester United finished a staggering 32 points behind Premier League champions Manchester City, highlighting the gap between the Red Devils and the top two.
The Red Devils lost to La Liga giants FC Barcelona and Wolves in the quarter-finals of the Champions League and the FA Cup.
