Arsenal reached the FA Cup semifinals for the first time since 2009 with a 4-1 win over Everton and Manchester United kept alive its faint top-four hopes in the Premier League by beating West Bromwich Albion 3-0 on Saturday.
Substitute Olivier Giroud scored two of Arsenal's three goals in the final 22 minutes as his team became the first to advance to the last four of the cup.
Mesut Ozil got his first goal in three months to give Arsenal a seventh-minute lead, Romelu Lukaku equalized in the 32nd before Mikel Arteta put the hosts back in front with a twice-taken penalty in the 68th.
It took the 61st-minute introduction of Giroud to turn what had been a tight contest against Everton.
The France striker, on for inexperienced and ineffective compatriot Yaya Sanogo, gave Arsenal more presence up front to allow the team's attacking midfielders to shine.
Alex Oxlade-Chamberlain was tripped by Gareth Barry for a penalty, which Arteta needed to convert twice — the first was ruled out for encroachment by Giroud — to give Arsenal the lead for the second time in the match.
Giroud sidefooted home Bacary Sagna's cross from close range in the 83rd and, after another flowing move, Ozil supplied a center for Giroud to apply another simple finish two minutes later.
Stopwatch: Arsenal 4 (M Ozil 7, M Arteta 68, O Giroud 83, 85) bt Everton 1 (R Lukaku)
City eye revenge against Wigan
Manuel Pellegrini insists his Manchester City side will not be distracted by their Champions League tie against Barcelona when they take on FA Cup holders Wigan on Sunday. Pellegrini's team trail Barcelona 2-0 ahead of Wednesday's last-16 second leg, but before turning their attention to the Catalan giants, City must focus on an FA Cup quarter-final revenge mission against the Latics at Eastlands. City suffered a shocking 1-0 loss against Wigan, who were then in the Premier League, in last season's FA Cup final. -AFP
