Ralf Rangnick confessed he was "not happy" with the open performance of his much-changed Manchester United side after they drew 1-1 with Young Boys in their final Champions League group game.
United were held by their Swiss opponents at Old Trafford after naming 11 changes from their last Premier League outing.
Mason Greenwood, who was partnered in attack by Anthony Elanga, opened the scoring within nine minutes.
Young Boys though hit back with a wonder strike from Fabian Rieder, whose efforts thundered into the top corner.
The visitors had the better of the second-half and, had they been more clinical, may well have secured a European double over the Premier League side.
Rangnick, who was in the dugout for only the second time, knew the risks he was taking by naming an XI that had hardly played alongside each other.
Nevertheless he was less than impressed with the end-to-end nature of the game, something he confessed he was keen to rid of during his first press conference.
He said: "I was fully aware before the game with this team we played today they haven't played together, not only with regard to formation.
"But also as a team the first half hour we did okay, we had a few unforced errors but at least we had control of the game.
"We should've been minimum 2-0 if not 3-0 up we had two great opportunities one from Amad and the other from Mata, but we didn't score we were a bit sloppy with those situations.
"We had a third one with Elanga so we could of scored 3 or 4 goals but we conceded the equaliser and we were not defending high enough not proactive enough and we could of also conceded more goals.
"So in the end if the score ended 3-3 or 4-3 nobody could've complained but as I said also the good things quite a few debuts game time for players who desperately needed game time so in total I wouldn't say I'm happy but it was okay."
When he first fielded questions less than a week ago Rangnick stated after United's 3-2 win over Arsenal that he wanted his side to have far more control.
He said: "As the future coach, we don't want those games every time because, in football, you have to minimise the coincidence factor and to have control on the game. That's my approach."
United's next clash will be at Norwich City on Saturday. The Red Devils are aiming to secure a third straight league win for just the second time this season.
