The Mariners have to pick up a victory if they are to keep alive any hope of progressing to the last 16 of the competition.

"The nerves of the boys are fine,  they know what they've got to do. We did alright against them in the first game and we should have won that game.
 
"We know what to expect, they've not conceded a lot of goals but not scored a lot of goals either but it's going to be a hard game," said McKinna.
 
"We're due for some luck to go our way and I feel as though it will tomorrow night and we're looking forward to the game."
 
Pohang Steelers are twice winners of the AFC Champions League and one of only four clubs to win back-to-back continental trophies since the inauguration of the competition in 1985.
  
The previous and only meeting between the Mariners and Pohang resulted in a 0-0 stalemate at Central Coast Stadium on an occasion where the visiting Steelers unveiled their gallery of talents, including well-travelled Brazilian strike pairing Denilson and Brasilia, FYR Macedonian international Stevica Ristic and a host of former or current Korea Republic national team contributors.
 
Most recently, Pohang recorded a 0-0 draw away to Daejeon Citizen in their local K-League, where they occupy ninth place from a field of fifteen after eight rounds.
 
The stalemate in Daejeon was Pohang's third goalless encounter in Korea or Asia since early March and during such time, the Steelers have only registered two wins from eleven attempts - form that will give the Mariners some confidence ahead of tomorrow's do or die fixture.
 
"It's make or break, we've had four AFC Champions League games and we've had three good performances but one very bad one and everyone remembers the very bad one," said McKinna.
 
"We need to get back to the do or die attitude that came back into our performance in Kawasaki and should we win on Tuesday, it sets up a great experience against Tianjin at Central Coast Stadium in a fortnight.
 
"It can definitely happen and there have been signs suggesting that it can happen but it has been a long time since we've won as everyone keeps reminding us.
 
"If we win tomorrow night, a lot of the other results are forgotten about and it would be great to then go on to beat Tianjin and go to the Round of 16."
