When Sporting's match starts, Porto's match will be over. If Porto has won, Sporting will have the motivation to win, not to miss it. If he has gelled, win to reduce the difference. Simple shows. I notice that Famalica's away is a chaos team. He scores goals (17) but also eats (22) in 10 except he has played. Sporting inside is at 2 goals average but also eats "half". I have the impression that the handicap is lucky but maybe it comes out (if it comes out) at the limit.
