The Gunners have been in top form recently, winning five out of their last six league games.
Everton are languishing in 12th position and their away record has been appalling, losing five out of their last six games.
Merson believes Arsenal will recover strongly after their disappointing defeat by Monaco on Wednesday and beat the Toffees with ease.
“Arsenal will win this match quite easily. Everton are struggling quite badly at the moment and only got out of jail last week with a last-minute goal at home to Leicester,” Merson told Sky Sports.
“It is Arsenal all over really, they will get back to normal and then their disastrous Wednesday against Monaco will all be forgotten about. So I do not see anything other than a 3-0 Arsenal win here.”
Arsenal’s good run of form in the league was reiterated by Arsene Wenger, and he is expecting his team to respond in a positive way following the loss to Monaco.
Wenger told a news conference on Friday: “We are third in the league, we are on a strong run, there is no obvious reason [to be against the team], we don’t play not to go down.
“We want to finish the season in a strong way and keep in this competition as well.
“We are in a strong run in the Premier League and we have to respond to that disappointment in a strong way on Sunday afternoon, that’s all we can do.”
The Gunners have dominated this fixture in the past and have a superior head-to-head record in the league, with 99 wins compared to Everton’s 59.
However, the Toffees have had a good record against them recently and Arsenal haven’t beaten them in the league since 2012, when they won 1-0 with a Thomas Vermaelen header.
