England take on the USA tonight in the World Cup semi-final in what is being described as the biggest game of women’s football this country has ever seen. Phil Neville’s Lionesses have enjoyed a brilliant campaign so far, brushing aside both Cameroon and Norway 3-0 in the knockout phases to reach the last four. England’s defence has been a key area of success, however, they will be coming up against an America side who have been free-scoring during the competition. Jill Ellis’ side have found the back of the net 22 times in their five games, firing 13 past Thailand in their opening fixture. With one of the best defences coming up against one of the best-attacking forces, we’ve decided to take a look at some key battles ahead of the crucial last four tie in Lyon.
