Pittsburgh Steelers head coach Mike Tomlin admitted on Friday it was "surprise" to arrive in London with a 0-3 record before facing the Minnesota Vikings at Wembley Stadium.
The Pittsburgh Steelers have the most Superbowls in NFL history.
But their start to the 2013-14 season doesn't suggest another triumph.
With a 0-3 record, Mike Tomlin's side sit bottom of the AFC North.
After Sunday's 40-23 home loss to the Chicago Bears, the Steelers are now in London for the league's latest Wembley clash.
Minnesota Vikings are the opposition - and something has to give.
Billed as the home team, the Vikings are also 0-3 and will be desperate to get off the mark at the expense of Pittsburgh quarterback Ben Roethlisberger and company.
At a pre-game press conference on Friday, defensive end Brett Keisel addressed the issue of turnovers - the Steelers have a minus-nine differential - while defensive back Ike Taylor highlighted the threat posed by Minnesota running back Adrian Peterson.
