Lahoz would be my odds-on, even if Spain is adjacent to Portugal. Though I haven't looked at the appointments for the qualifiers, what's to stop someone being appointed 48 hours after a previous game? That's "standard" if you're in the Europa League on a Thursday & then back in your country for a Saturday. Otherwise, if England lose then I'd think Kuipers. And if the Spain/Portugal neighbour relationship is an issue then Zwayer. With others away in Poland for the U20, the options (with the 48 hour gap) are limited. Kassai would be a shoe-in were it not for his team's most recent form. And if England do go through, would UEFA appoint Collum rather than Lahoz? This is the most fundamental issue - perception!
