Coach Jorge Jesus insisted Benfica should’ve beaten Juventus by more than 2-1  and were denied “a clear penalty.”
The first leg of the Europa League semi-final went to the hosts in Lisbon and the decider is next Thursday in Turin.
“We were justly winners,” Jorge Jesus told SCI after the game.
“We could’ve scored more goals, in fact. The referee did not give us a clear penalty on Enzo Perez.”
The incident occurred in the second half when Enzo Perez ran into Martin Caceres in the box and fell over his leg.
Juventus had 57 per cent possession in Lisbon and Benfica scored with their only two shots on target.
“It was important to get the victory, but would’ve been more important to win 2-0 rather than 2-1. The tie is still open, but we’re in a stronger position in Turin because we won.
“We knew that we were facing a great team and even while being defensive Juventus usually score goals.
“We had to be perfect defensively and came close to achieving that. We only had a few difficulties on the Carlos Tevez goal, as that was great individual play.
“It was a spectacular game between two great teams and the first Juventus defeat in this Europa League. I think both sides showed what they can do and it was worthy of a Champions League tie.”
