OR you could look at it like this;
Robles -- reserve keeper unwanted at atletico who are choosing to continuously loan a keeper from another team rather than give him a chance. Also, you can add that he's done nothing of note since emerging onto the scene at the same time as de gea.
Deulofeu -- 19 year old loan signing. It's an interesting move but he's just a kid on loan at the end of the day, not really building for the future is it?
Kone -- Average forward who shone in a poor team whose attacks all went through him. Overpriced, no re-sale value and not good enough for a top 6 side.
Alcaraz -- Spat at someone. Not had much of a career and seems to be injury prone. Not quite Jagielka or Distin level is he?
You can't give the argument that they are replacing neville / hitzlesperger either. The key argument is are they good enough for a top 6 side -- the answer is no. Deulofeu may surprise us for a season but the others would have had more success if they were decent.
