The story of last week's Champions League ties were of experienced European powerhouses Juventus and Real Madrid respectively edging past Tottenham and Paris St Germain, both comparatively green at these stages of the tournament.
"We have to be at our best level and be able to compete".
But the veteran midfielder is convinced that Manchester United's future is safe thanks to Scott McTominay.
The Spain global said: "I don't think about City, just about us".
"To keep going and try to get through to the quarter-final would be great for us".
He said: "We're close to achieving something significant after 60 years without reaching the quarter-finals". "We are playing against a team who didn't lose against Liverpool home and away, scored goals at Liverpool and drew the match in Liverpool", he added.
With seven goals in La Liga, the Argentine is yet to score in the Champions League.
"I do not feel like we have any advantage at this moment".
"We have put a lot of planning and preparation into this game with different strategies and ideas on how we can hurt them".
With Manchester United holding the aces on the defensive front, they only just tip the scales in their favour, which is why The Hard Tackle predicts a narrow 2-1 win for Jose Mourinho & co.
The midfielder confirmed it will be his last season at Old Trafford and revealed the logical transition to Jose Mourinho's coaching staff in the off-season.
"Jurgen Klopp claimed the referee cost Liverpool a point at Old Trafford, but I wouldn't agree with him on this occasion", states Aldridge. "There are plenty more to play, and as long as I am playing well and the manager's happy, I want to be pulling on the shirt".
"What would have happened if Mohamed Salah had fallen over like most Premier League players would have done?"
"You have to take it into the game, and today it worked". Juan Mata and Marcus Rashford also were far more comfortable in their roles while United caught Liverpool on the counter repeatedly in the early minutes, leading to Rashford scoring twice.
