Sue Barker introduces live coverage of men's semi-finals day at Wimbledon.

Andy Murray has already eclipsed Henman's highest world ranking and many believe he can go further than his former Davis Cup team-mate did on the SW19 grass. Getting to the semi-final would be a start as Murray has never previously got beyond the last eight at Wimbledon.
