It's Dani's positional (un)awareness.. Over and over again...
I really think there are some (maybe many) games that he needs to just stay at the bench.. Montoya would be far better tonight..
But also regarding offense:
There is also something that i noticed lately.. As years go by, he becomes less and less dangerous near the opposition box. He rarely tries to shoot, penetrate or make accute crosses. (Of course there are times he does, see spartak goal.. But these times become less and less..)
If you put a video of dany 08-09 and dany 12-13 i think the difference is more than noticeable..
