Portugal look to be out of sight in the clash after Bernardo Silva's low strike beat Lukasz Fabianski.
The West Ham goalkeeper will be unhappy that the attempt beat him, potentially putting the game beyond his team.
Silva made the goal for himself, cutting in from the right hand side and working the ball onto hs left foot.
His low drive squirmed through the former Arsenal and Swansea man at his near post, leaving him ruing his mistake.
Poland had taken the lead on the night, but Bernardo Silva competed his team's comeback, with the result likely secured.
