What I don't understand about Spurs is why Ramos plays them 4-1-4-1 with one man upfront, virtually on an island. I mean, Spurs LACK organization, discipline, concentration right now. And that's what you need to pull off a conservative tactic. I'd say send your masses forward. Even if you go tits up, losing 4-3 feels better than 1-0 again. That and you can force things here and there.
In desperate times, gutsy calls are needed. Ramos fails.
