I think that a few people are overreacting with what Poch is saying in that press conference.
The Lamela question, the guy practically answered his own question saying Lamela looked sharp and Poch pretty much said, you said he looked sharp what more do you want me to say about it?
Regarding transfers, Poch clearly states that he has no involvement in the negotiation of contracts or players coming in / going out. He did not say anything about not having a say on incoming transfers.
Looks to me that Poch is getting fed up with the same questions being asked about transfers and is saying that he is here to coach the team while Levy deals with transfers and contracts, it is not football manager, the manager very rarely gets involved with the negotiations of players, they might meet the player and speak to them but i would imagine thats about it. Do you really think the chairman says here is £90m and £500,000 a week wage budget knock yourself out? It doesn't work like that.
