Cook was a part of the 3-0 win they secured at Chelsea in January. But he does not want that performance to feel like a one off.
When asked about that famous result in January, Cook told the Daily Echo: "That night was incredible – probably the best night we've had. It was an amazing performance all-round.
"I hope it's not a once-in-a-career result. We back ourselves to get the win and have no real pressure on us, so why not?
"It's our fourth season in the Premier League and we feel we are Premier League players.
"As you have seen in the past two league games, we have a willingness to never give up and grind out results – that comes with the experience we have gained in the past few years."
