The Trotters pushed Arsenal all the way at Highbury as well and the big defender also believes that although last season's three wins against Sam Allardyce's side at the Lane might give us a slight psychological edge, they really count for nothing this time around.
Dean said: "We played them three times last season, won all of them, so that won't give them too much confidence but at the same time they've a few new players in this season and they look quite strong again.
"They've had some good results away from home, won again at Old Trafford, so we can't underestimate them. We'll give them a lot of respect but at the same time we'll approach it in a confident frame of mind.
"The Premiership game here last season is the game where they had their strongest side. That's more of a gauge. It will be a tough game, no doubt about it.
"They look to hit teams on the break, have good pace down the flanks and up front. They get a lot of men behind the ball and hit you on the counter.
"It will be a tough game but a game we're going into with a lot of confidence.
"We had a good result at Blackburn, going into it on the back of a win and it's a chance to put things right after the last home performance as well."
Meanwhile, we asked our friends at Opta Index to take a look at Deano's stats up against returning ex-Spur Gudni Bergsson - here are their head-to-head findings.
