LISBON, Portugal -- FC Porto missed a chance to take the lead of the Portuguese league after drawing 1-1 at home with Setubal on Sunday.
Porto was chasing a 10th straight league victory that would have moved it above Benfica at the top - one round before the two rivals meet following the international break.
Benfica was held 0-0 at Pacos Ferreira on Saturday.
After Jesus Corona put Porto ahead in first-half injury time, Setubal equalized through Joao Carvalho early in the second half.
Defending champion Benfica is one point above second-placed Porto with eight rounds to go.
"We still control our fate," said Porto coach Nuno Espirito Santo. "It's important that we recover from this setback."
