Tactics Yeah I think this is the correct analysis. It's a pretty decent game plan from us too; our mistakes have been individual. You can't push up too far when Sporting are playing two central forwards. One misstep from Saliba and they've put you at a disadvantage. That's how PSG got done.
We do need better width though. I'd maybe take off Trossard or Madueke for Marty early in the 2nd half. Trossard because he has offered none, and Madueke because all he does is mess things up even though he takes up the right positions. We need to get the ball out there quicker too and Zubimendi is having an off day, hoping he can improve a bit as the game goes on.
