Manchester United record a winning again at home, amazing. Manchester City lost, but I'm not too surprised, because they also don't have to be too serious in the last game of the Premier League. Their target has also been completed in the Premier League, and it seems they are also ready for the Final FA. I was just surprised by the results of Liverpool vs Southampton, Liverpool were very kind in that last game, they gave Southampton a good experience.
The most important game for Juventus United is the next game when they are going to face Manchester City in FA final match where they can have a chance to beat Manchester City, however, I think Guardiola will never let Manchester United take the chance of winning the second trophy of this season because he even aims to win all the three tournaments with Manchester City.
I also see no possibility of United winning ahead of City. As you said, no way that City with Guardiola will let United be better than them. United should transfer 4-5 points. First of all, I think it's Kane for forward, Tielemans for midfielder, Kim Min Jae for centre-back, Barnes left wing, Madison at number 10. If it were me, I'd buy these 5 players. Kane scores 20-25 goals for sure. Min Jae does a great job at the centre-back. Even though Barnes-Madison couldn't save Leicester City with goals and assists, they make a big contribution to United. Tielemans again forms a terrific trio with Casemiro-Fernandes. These are very specific suggestions but I think you can see my meaning. Nevertheless, City with Haaland and Guardiola will be better than United in any case.
