If Azpi had played on the right vs United and City we wouldn't have dropped points. Don't compare Ash to Luis, Luis right now is better than Ash was last year. Ash got burned by Robbem vs Bayern with Roma. Luis doesn't get burned.
Against Sunderland he could have handled it, they aren't great offensively. He has been great when he plays in the CL, he has to play to adjust to the PL, he's good enough to be given that opportunity.
Besides that 8-0 drubbing to Soton they would have the 2nd best defense in the PL. There's a reason they have 8 draws. City will probably draw them too.
Yea, absolutely, but that doesn't mean he's injury prone. I don't blame Dortmund, they have to do what they can, but to call him injury prone is ridiculous. Look at that team, they're always hurt, is half their team injury prone?
