Fellaini's late goal was really United's only talking point of the entire game.
"Can myself or another manager have a reaction or frustration?"
The relief around Old Trafford when Fellaini turned to fire his effort through the legs of defender Loris Benito was so pronounced that United's emotional manager Jose Mourinho picked up and hurled the pitchside drinks holder to the ground.
"Of course, we're all disappointed but we need to fight for the club and for the team and for the manager starting tomorrow".
The result, coupled with Valencia's 1-0 defeat to Juventus, means the Red Devils join the Italians in booking a spot in the knockout phase with one group game to spare.
Meanwhile, someone else said: 'I haven't played football in like seven years but I'm nearly 100% sure my first touch is better than Lukaku's'. We didn't play for that, for a 0-0.
It wasn't just about United's late victor.
"Without David [de Gea's] save, no winning goal", said Mourinho, in reference to his goalkeeper's goal line stop from Ulisses Garcia. You could be nice to me and say "Jose, you played Marcus Rashford as a No.9" and go from there.
"Sometimes it's better that you compete throughout the week against each other to play well at the weekend together". "We had the chances to be three or four goals in front but we still needed that unbelievable save from David", the full-back said.
"[I've] had 14 seasons in the Champions League and 14 times I've qualified through the group stages, they've never stayed in the group stage".
"So in 16 years, 14 times I qualify and two Europa Leagues, just a little curiosity for my lovers and lovers of the stats".
Mourinho dropped Paul Pogba and Romelu Lukaku to the bench against Young Boys while Alexis Sanchez was left out completely despite being fully fit. Your team are not playing the way they're expected to play.
Rashford hit the side-netting against a Young Boys side that, while second best, offered a threat on the break, with Djibril Sow wasting a great chance to capitalise in stoppage time as his flick bobbled wide.
He told Bleacher Report: "Obviously you sign here to win as many trophies as you can".
PSG are said to be his most likely destination given they are one of the few who can afford his wages. "We know what he's won".
