Think you've nailed it.Right. The three time defending European Cup winner just quit because he felt he couldn't possibly sustain that level and wanted to eject before the train crashed.
If being in that sort of fishbowl is what Poch in fact wants (dubious), he only gets one chance. This would be a very stupid situation to wager that chance on. His Spurs tenure plus a high-profile failure at Real before he can even implement his ideas would lock him out of the Argentina job, the PSG job, all these positions he might want. If he's going to get stuck at the Valencia's and Newcastle's of the world the rest of his career, why not stick it out at Spurs?
Think Poch's dream future career would be Spurs>PSG>Argentina>Espanyol
He doesn't seem the type who will have 7-8 clubs managed. He'll win us some trophies and likely leave at the end of this contract. Say 10 years with us. Then he's built up enough creds to go where he likes, which are the clubs he loves.
