Castro bemoans disallowed goal

Porto interim coach Luis Castro was pleased with a 1-0 UEFA Europa League win over Napoli, but felt his side should have had a second goal.

Jackson Martinez struck in the 57th minute on Thursday to hand Porto a narrow advantage ahead of the second leg of their last-16 tie in Naples.

Castro was understandably happy to see his side deny Napoli an away goal but he was less impressed with a decision that saw Carlos Eduardo's 19th-minute header ruled out for offside.

"We've had access to the images and the response is natural. The goal is clear. We should have won 2-0," Castro said.

Reflecting on the positives as Porto claimed a first victory in eight European games, Castro told Sport TV: "Our goal was to win without conceding a goal and it was achieved.

"We won well. Victory suits us well, but I get the feeling that we could have won 2-0."
