Manchester United boss Ole Gunnar Solskjaer was forced to defend the reasons behind his substitutions after his side's defeat to Swiss champions Young Boys in the Champions League.
Cristiano Ronaldo - who had put United ahead - and Bruno Fernandes were replaced as the 10-man visitors, who had Aaron Wan-Bissaka sent-off, were drawing 1-1.
A mistake by Jesse Lingard - who had replaced Ronaldo - allowed Jordan Siebatcheu to score the winner in the 95th minute.
Solskjaer said: "The game had gone 70-odd minutes, they had been running a lot on Saturday and today. We wanted Nemanja [Matic]'s experience to keep hold of the ball and Jesse [Lingard]'s legs."
United captain Harry Maguire said Lingard was not to blame for the result.
"That’s football. People make mistakes – we’re not blaming Jesse," he added. "I’m sure everyone on that pitch today has made a mistake. I’m sure Jesse will pick himself up."
