I agree with the points you have raised. Spurs must do more to sign new players etc. But I cannot help think that Poch is going about it the wrong way. He ought to talk to Levy without using the media. He is effectively strong arming levy and using the media as a tool.
This is what ruined Redknapp, talking to the media about his wishes to be England's manager.
Levy has done a lot for Poch. Gave him a very good package, same for Kane. Yes, he needs to do more but by the same token, levy can argue that Spurs are succeeding by spending so little, whilst creating new infrastructure that is world class.
Yes, talk to levy about what he can do to get Spurs to compete for the league title etc. But don't use the media.
