Hussain said: "You can't expect people to score runs all the time, however good they are. Even the likes of Michael Vaughan and Sachin Tendulkar will go through periods when they don't score.
"Marcus Trescothick is a very fine player and his cricketing ability has never been questioned. He is a big player for us."
Not even a victory under the Kingsmead floodlights tonight can guarantee England a place in the Super Six second stage.
But if they are left needing to beat Australia in Port Elizabeth on Sunday then that will merely give Trescothick an even bigger incentive to take some revenge for his disappointments Down Under.
The pressure, though, would be enormous on every member of Hussain's team.
"We haven't really been tested yet in this competition," said the captain ahead of today's meeting with India.
You know what he means so far as the victories against Holland and Namibia were concerned - although even Namibia had England sweating for a time.
But Hussain's men were certainly challenged to raise their game in Cape Town when Pakistan had them tottering on 118 for five.
The response from that point indicated a spirit strengthened, rather than weakened, by an arduous and often painful winter.
"We are definitely together as a side," said Hussain. "Even in a very difficult winter we have always stuck together.
"But it's easy to talk about how you are together when you're playing Holland and Namibia or the ball is swinging around for you against Pakistan at Newlands. The difficult games are still ahead."
They started today in a city with a big Asian population that was expected to turn out in force to support India and give England's always vocal travelling fans a good contest.
