Lucho needs to fix these 3 problems.
1. Set pieces.
2. Interplay between CMs + Messi (Iniesta-Busi-Rakitic-Messi), less balls directed towards Alves/Alba, more balls towards the center area of the midfield. Less wing play, he's becoming obsessed with playing on the wings.
3. Stop this nonsense with both fullbacks very high up the pitch. You can't have a 2 men defence. Either he switches to a 3-4-3 or one of the fullbacks stays back more often.
I'm not even gonna count motivation. That's a must in any team that wants to win smth.
If he fixes these problems we can have a shot at titles this season, including CL. Other than Chelsea, no big team looks menacing now. Bayern, Real and us, all have issues we need to deal with.
