Sporting Lisbon has been playing flawlessly and has won all seven games. Benfica has been doing a bit better recently, but there is a five-point gap between them and the leader Sportek Lisbon. The match in December is very important to close this gap. Benfica will definitely need to win that match. If Sporting Lisbon loses points before that match, Benfica may even be in the lead.
Sporting will sooner or later lose points, it will be difficult to always maintain this pace. It can happen, but difficult.
Benfica, on the other hand, is prohibited from losing any more points, at least until they play Sporting.
On the other hand, Benfica and Porto should have more games in this round, if the club world championship takes place.
So this championship will be really interesting, if the Big 3 get into a good winning rhythm, as is starting to happen.
