I don't think the biggest issue is persuading Poch to choose Utd over Real but persuading him to leave Spurs. There's no urgency for him to leave - he's only going to have more offers come his way as and when the PSG, Bayern and Barca jobs become available. Unless the Utd job is 100% right for him then I can't see him leaving, especially if Spurs qualify for the CL and Utd don't. He could stay at Spurs and finish 5th and it'll do less damage to his reputation that taking the Utd job and finishing 4th.However, as Baz mentioned, that could be problematic if we want Poch as it would take some effort to get him (unless Mourinho ends up at Real first).
