The big defender had tunnel vision at Highfield Road - it was all about keeping a zero in the goals against column.
He achieved his aim as goals from Robbie Keane, Fredi Kanoute and Rohan Ricketts won the second round tie 3-0.
"Keeping a clean sheet was very important," said Anthony. "We spoke about it before the game and that was our only thought - myself, Carry, Deano, Kasey and Tano, to get a clean sheet.
"We decided we hadn't done enough recently, let in a few goals and it had to come to a stop.
"It's very nice to have kept a clean sheet. When it reads 'opposition nil' on the scoreboard, we've done our jobs as defenders. You won't lose a game and at the least you'll get a draw. That's what we're looking at from now on.
"The win was important for morale more than anything, confidence. We've had a bad time recently, three defeats on the spin and it was all about getting a win."
