Rangnick and Manchester United know what they are up to, I am sure they will be to navigate through these games and grind some results.
They are not clear about what they should do, about their strategic plans short term and long term. They are fluctuating and unclear about what term they should choose and focus on, short term or long term. Consequently they are not decisively on whether they should sacrifice one or two seasons for long term plan or they will try to achieve something as short term plan.
I see Manchester United are not qualified enough to achieve any big in short term. So why do they not sacrifice a few seasons in order to build up their team and achieve something big in long term? Liverpool need a few seasons with Klopp to win Champions League and Premier League.
The game against Manchester City is a derby game and games like that are unpredictable. Irrespective of the forms of the teams, the weaker team at moment may spring surprises in a derby game but the inconsistency of Manchester United makes it difficult for anyone to give them chance against City or Tottenham. They should be able to make it through to the next round in the champions league because obviously they are having advantage from the first leg.
It will be a hard derby for Manchester United. Manchester City need to win it to maintain their advantage against Liverpool. Manchester United will face with terrible future if they lose the derby because Arsenal, Spurs are behind and can take over the 4th position of Manchester United.
I think United will begin this match with more pressure than City and perhaps result will be a win for City.
