The two sides have had contrasting fortunes so far this season, with the Baggies sitting fifth in the Premier League table, five points and five places ahead of the Gunners.
The 31-year-old Nigeria striker was part of them team that stunned Arsene Wenger's side in a 3-2 win two seasons ago and is hoping to repeat that feat on Saturday.
“I have good memories from 2010, I’d only just arrived in England and we went 3-0 up which was hard to believe,” Odemwingie told The Mirror.
“It would be less of a surprise if we were to get a result now.

“They still have quality but we’ve been strong this season so we think we can go anywhere and beat any team.”
As a striker, Odemwingie knows the importance of a confident front man for a team. He believes the Gunners are still missing former captain Robin van Persie after his summer move to Manchester United.
He added: “He scored goals and inspired his team-mates, it was a big loss for them.
“Maybe they haven’t forgotten the influence he had and it is taking time for them to find something which will work for them.”
