BIRMINGHAM, England (AP): Ollie Watkins scored again as Aston Villa knocked Bologna out of the Europa League in a 4-0 rout yesterday to set up an all-English semi-final against Nottingham Forest. Unai Emery’s team reached its second European semi-final in three seasons with a 7-1 aggregate victory. Watkins had netted twice in last week’s 3-1 win in the first leg of the quarter-final in Italy, and the striker set the pace at Villa Park.
