For me Stepanek - Ferrer is a more interesting match. If Steps wins this tie will be finished, is a Davis Cup point for czechs.
Berdych-Almagro will be 3-0 or maybe 3-1 in 2h.
I don't think Stepanek is going to trouble Ferrer too much. In Paris Ferrer easily dismantled Llodra after some 5 service games.
