The Gunners have won just two of their last five fixtures - both in the FA Cup against non-league opposition - and Arsene Wenger's men will be determined to get their bid for a top four finish firmly back on track by winning this one.
Arsenal have attained that objective in each of Wenger's previous 20 seasons in north London and it is a record that the 67-year-old boss will be reluctant to relinquish, especially given speculation that this season could be his last at the club.
The Gunners have taken full points from just one of their last six Premier League games on their travels, but they remain as bet365's 7/10 (1.70) favourites to bag a vital victory here, while the same firm go 11/4 (3.75) that the match remains level at the end of 90 minutes.
West Brom have won seven of their last nine Premier League matches on home soil and the Baggies can consolidate their place in the top half of the table by heaping yet more misery upon Wenger's men; bet365 offer Evens (2.00) that Pulis' side pick up full points from this fixture.
Albion, though, come into this clash following back-to-back Premier League defeats against Crystal Palace and Everton respectively; the Baggies conceded five goals without reply in those matches and the Gunners will hope to expose any defensive weakness in the home side's armoury.
West Brom have conceded in seven of their last nine home fixtures, while Arsenal have scored in 20 consecutive matches away from home; bet365 offer 7/10 (1.70) that both teams are on target here, while the same firm go 8/11 (1.73) that this match produces more than two goals.
Arsenal were beaten 2-1 on their last visit to the Hawthorns, but that was their only loss in their last 13 games against the Baggies and Wenger's men can get back to winning ways in the Premier League by picking up all three points from Saturday's showdown.
The 7/10 (1.62) quote for an away win, though, looks to be somewhat skinny; better value may lie in backing Arsenal to win and more than two goals to be scored when these teams meet.
The selection would have seen punters profit from all but one of the Gunners' last eight away wins in all competition and the 7/5 (2.40) quote for the trend to continue looks like decent value once again this weekend.
