The recent cup visit resulted in a 4-3 win on penalties for the Gunners (the match finished 1-1 after extra time), but it'll be a different line-up this time as Wenger's side go for an 11th straight win in all competitions.
Good afternoon and welcome to our live blog of the second set of Premier League games of the day.
Our main match sees two sides high on confidence go head-to-head. West Brom were winners at Old Trafford last time out and will be keen to claim another scalp against Arsenal today.
The Gunners, though, are in fine fettle themselves, having registered a series of great results since opening-day defeat to Aston Villa. Something's got to give.
It doubled Albion's win tally for the season, and coming on the back of a 3-0 home win over Sunderland was further evidence they are perhaps settling down after a rocky start that had seen just two points accrued from the opening four games.
Arsenal travel to the West Midlands having won their last eight away matches in the league, and their recent record at The Hawthorns is good, too, winning on three of their last four visits.
Albion have lost two out of three at home so far, but face this test in much better shape than they would have been just a couple of weeks ago.
