On Wednesday night, Rooney chased down every ball and always wanted possession in a performance that embodied United’s fighting attitude against Olympiacos – it looked like a United of old were in action and it was a dramatic turnaround from the humiliation against Liverpool just three days before, something Rooney was eager to fix.
“I’ve said before that our performances this season haven’t been good enough and we owed the manager a big performance,” he said.
“We know as players we are better than what we’ve done this season and as a group we have to show that and put it right.
“After the first game in Athens and especially what happened on Sunday, we knew that we had to come and give a big performance, for ourselves really – for our own personal pride, and the manager and we’ve done that.
“It’s something we have to kick on from now. We’ve still got a few games left in the season and we want to build on this. Hopefully we can do that.
“I think Sunday, as all the players will admit, was a devastating result for us. To lose 3-0 the way we did was hard to take and we had to stand up and show ourselves and really be at our best because that was not good enough.
“We have done that, but we have to kick on now and we have to give performances like that every week.”
Rooney also discussed the DNA of United and touched on the ripple effect that had been caused at Manchester United this season because Sir Alex Ferguson.
“I think it was always going to be tough when Sir Alex left,” Rooney added .
“It was obviously a massive change so we knew it was going to be tough, but we didn’t expect it to be as tough as it has been.
“But we have to put that right. We have to keep working, keep believing in ourselves and hopefully it’ll get better.
“We (players) talk after every game, whether we win, lose or draw, but we knew as a team what went wrong on Sunday, we didn’t need anyone to tell us, and we came out and delivered a big performance.”
“If it’s not going right, some games you can have bad games, but you still need to put that effort in. It’s massively important to me, to the team and the manager.”
