The turning Mohali wicket has been under the spotlight with Proteas opener Dean Elgar calling it a bad cricket wicket, but Henderson said that the visitors expected this kind of tactic from the hosts.
"We have lost quite a bit of wickets now, only on day two really. We have seen a lot of wickets fall. It's going to be difficult. The question will always be why didn't our spinners turn it more than theirs.
After part-time spinner Elgar turned out to be the unlikely hero of Day 1 by bagging a four-wicket haul, Ravichnadran Ashwin, who bagged a fifer today, made it count for India on the second day.
India now hold an edge after managing a 142-run second innings lead, and Henderson admits it will be tough for the visiting batsmen.

Leg-spinner Imran Tahir was brought into the attack after Elgar and off-spinner Simon Harmer in both the innings and Henderson, who played seven Tests and four ODIs for the Proteas national team, was also surprised at the strategy.
