Arsenal are a win away from securing their 17th consecutive Champions League season while West Bromwich Albion find themselves in a similar position as they inch toward Premier League safety.
They'll meet on Sunday at the Emirates Stadium as the Gunners try to extend their Premier League-best 17-match home unbeaten streak.
With two matches remaining, Arsenal (22-7-7) are four points clear of Everton for fourth place in the Premier League.
"To get over the line is always difficult," Arsenal manager Arsene Wenger said on Monday, after his club's 3-0 home win over Newcastle United.
West Brom (7-15-13), meanwhile, are four points above the relegation zone with three matches remaining and a game in hand over the table's bottom three teams.
"This win probably gets us within touching distance of safety but we're not safe yet, it's as simple as that," Baggies goalkeeper Ben Foster told the club's official website after Saturday's 1-0 victory over West Ham United at the Hawthorns. "We need to crack on. We've got Arsenal, Sunderland away and then Stoke at home and I'd like to think we'll get four to six points from them, so hopefully it will be a strong finish."
They can put any question of relegation to rest with three points at the Emirates, though Arsenal have compiled 12 wins and five draws at home since losing their season opener to Aston Villa on Aug. 17.
Overall, the Gunners have won three straight by a 9-1 total against Newcastle, Hull City and West Ham after going winless the previous four.
Against the Magpies Olivier Giroud scored for the second time in three matches, while his compatriot Laurent Koscielny and the club's record signing Mesut Ozil also scored.
"You could see there is a harmony in the team again and our fluency is strong," Wenger told the club's official website. "We look always like we can create and for a while we had problems on that front. Now that people are back and everyone is confident again you can see that we always look like we can score.
"It is about getting over the line and finishing the job (to secure a top-four place) now. We want to do it on Sunday against West Brom, who are a dangerous team as well."
Arsenal have four wins and two draws against West Brom since losing to the Baggies 3-2 at the Emirates on Sept. 25, 2010. One of those draws was a 1-1 final at the Hawthorns on Oct. 6. Claudio Yacob gave the home side the lead in the 42nd minute, but Jack Wilshere, currently sidelined with a fractured foot, evened the score in the 63rd.
That followed the Gunners' triumph in penalties in a 1-1 League Cup meeting on Sept. 25, also at the Hawthorns, in which Arsenal's Thomas Eisfeld and West Brom's Saido Berahino took care of the regulation scoring.
The Baggies have put themselves in a position to secure safety thanks to two wins and two draws in their last five, the only loss coming at title-contending Manchester City on April 21.
They rebounded from that with the win over the Hammers, which featured top-scoring Berahino's 11th-minute strike. It was the 20-year-old forward's fifth in top-flight matches, in which he's accounted for four of their seven winners, and ninth overall with just 11 starts.
West Brom should have key defender Gareth McAuley back after missing the last two matches with a calf injury. Fellow defender Steven Reid could miss the match after a groin injury forced him out of Saturday's win.
