The Gunners head into the trip to Merseyside looking to get bounce back after the disappointment of their 2-1 loss to Watford last weekend.
Arsenal have struggled to find consistent form in the Premier League this season and the north London side currently find themselves sixth in the table and nine points behind leaders Manchester City after eight games.
Arsene Wenger’s men have already lost three of their opening eight games to leave their title hopes in serious doubt.
However, former Arsenal star Merson is tipping the north London side to bounce back when they take on Everton on Merseyside this weekend.
Speaking to Sky Sports, Merson said: “Which Arsenal will turn up? The one we’ve been raving about for a month before Watford? Or the team who turned up at Watford?
“This could be a must-win game for Ronald Koeman on Sunday. You look at Craig Shakespeare’s sacking, and Leicester were always tipped to finish mid-table. Everton were a shoe-in for seventh, at least, and Koeman is under severe pressure. They could be in the bottom three after this.
“I’m going for Arsenal. I know they were beaten at Watford, but Everton are not a team who are going to kick you off the pitch. Arsenal will be more comfortable playing against them.
“Koeman bought a lot of the same in the summer, and lost Romelu Lukaku. I don’t think it was money well spent.”
Arsenal are aiming to challenge for the Premier League title this season after they finished fifth in the table last term.
The Gunners have not lifted the top flight trophy since their famous unbeaten triumph in the 2003-04 campaign, when they were still playing their home games at Highbury.
They have, however, won the FA Cup in three of the last four seasons and beat Chelsea in the Wembley final back in May.
