Arsenal boss Emery is aiming to get one over on Liverpool, who has enjoyed some positive results against the Gunners in recent years.
The Emery era is, however, beginning to take shape with the club winning 11 of their last 12 matches.
Arsenal were finally stopped from win No 11 last weekend with Crystal Palace emerging from a pulsating clash at Selhurst Park with a point to their name.
Jurgen Klopp’s rampant Reds currently sit second in the Premier League table, behind Manchester City on goal difference.
They are also one of three teams – Chelsea and Manchester City also – who are unbeaten at this stage.
And Keown thinks Arsenal cannot afford to lose if they are to have any chance of making the top four.
He told the Daily Mail: “I think this will be a 2-2 draw.
“Liverpool will go for them but Arsenal has a formidable home record.
“If Arsenal wants to make that step back into the top four, they cannot afford to lose this game.
“The fans want to see Arsenal getting results against the big teams.”
Known also believes Arsenal are playing a risky game by allowing Aaron Ramsey to leave the club after 11 years.
“From the club’s point of view, they have made a decision and are not letting themselves be dictated to by a player,” he added.
“If they wanted to keep him, they surely would have left the door open and tried to find a solution financially.
“I expect Ramsey to continue to be 100 per cent committed to the cause.
“He is a fantastic professional who will give everything to the football club.
“But I do find it staggering that the contract offer has been removed.
“When you think about how much it will cost to replace a player like Ramsey, it is astonishing that he will be allowed to leave.
“The club must have already identified targets who they feel represent better value for money.
“In an interview at the weekend, Raul Sanllehi – Arsenal’s head of football – said that they started identifying last summer’s signings in February and March.
“At that time, Arsene Wenger was still in charge. Unai Emery had not been appointed.
“Who is making the decisions on transfers? And how privy is the manager to these decisions?”
