The defenders were caught ball watching on the goals. Especially Clyne. And Gomez.
We really miss Van Dijk when he's not on the field. Anyone who thinks there's a 1st, 2nd and 3rd choice defender to partner him is way off. There's Van Dijk, and then there's anyone else
Attack was a bit muffled, but Wilson was VERY clever with his runs, and Fabinho kept trying to find him. Good to see.
Brewster has balls. I'd keep him and Wilson in the first team squad for the season.
Larouci didn't do too bad at all. A bit naive, but that's what experience is for.
Kent had some moments.
But Dortmund's defensive organisation was well impressive. They just didn't like to give up any space at all. Quiet shout for next year's Bundesliga perhaps?
