Stopping the initial onslaught of destructive opener Virender Sehwag would be the key element of the home team's pace attack against India in the cricket Test series starting here on Thursday, according to South African fast bowler Morne Morkel.

Morkel, who will pair up with world's top-ranked bowler Dale Steyn in the first Test, said Sehwag's wicket early in the innings would be vital to their chances.
