The goals helped the relegation strugglers to a 2:1 win over the visiting Gunners.
Morocco star Adel Taarabt scored his first goal of the season to give QPR the lead after 22 minutes when he turned Thomas Vermaelen on the edge of the penalty area - after receiving a pass at the halfway line - before striking to the bottom corner.
Theo Walcott equalised for Arsenal fifteen minutes later, but on-loan Samba Diakite, 23, made sure of the points when he dispatched a Jamie Mackie cutback in the 66 minute.
Also on target in England were the Nigerian pair of Victor Anichebe and Victor Moses. Both sealed identical 2:0 wins for their clubs Everton and Wigan respectively.
Victor Moses ensured all three points against Stoke City when he rounded goalkeeper Asmir Begovic in stoppage time to slot home his fourth goal of the season and give his club hopes of surviving relegation.
Wigan are second from bottom and still have much work to do to stay in the top-flight, but they are within touching distance of a clutch of teams immediately above of them.
Victor Anichebe also grabbed his fourth goal of the season to help Everton to a win against West Brom. Playing just his ninth league game of the campaign, he hammered his effort in off the post on 68 minutes, following good work from South Africa midfielder Steven Pienaar.
The striker had been on the field just six minutes before making his presence felt.
Cameroon striker Eric Maxim Choupo-Moting came on at the start of the second half to score twice for Mainz 05 on their way to a 3:0 spanking of home side Werder Bremen in the German Bundesliga on Saturday.
Hungarian striker Adam Szalai, who Choupo-Moting replaced at the break, had given Mainz a first half lead before the African hitman shot to the bottom corner on 48 minutes for his ninth goal of the season.
The 23-year-old's tenth goal of the campaign came from close range in the 74th minute to seal the win for Mainz, who remain in tenth place on the table.
The brace makes the Germany-born Indomitable Lion the top scoring African in the Bundesliga as he overtook the nine goals scored by Senegal striker Papiss Cisse before moving to Newcastle United in the January transfer window.
Mali midfielder Bakaye Traore scored for the second week running to help Nancy to a shock 2:1 home win over title contenders Paris Saint Germain in the French Ligue 1.
Traore, who scored the lone winner in last week's victory at Brest, struck his side's opening goal in the 18th minute and PSG had no reply until the break.
Five minutes after the restart, fellow Malian Momo Sissoko pull PSG level, but French midfielder Yohan Mollo snatched the winning goal on 89 minutes after good work from Cameroon striker Benjamin Moukandjo-Bile.
The defeat leaves PSG in second place on goal difference, while leaders Montpellier have a game in hand.
In a different game, Mali forward Modibo Maiga scored late in the second half to ignite a 2:1 comeback win for relegation-strugglers Sochaux over visitors Brest. It was Maiga's sixth goal of the campaign and his second on the bounce.
Saint Etienne's European hopes were dented after they lost 3:2 at home to lowly Nice. Cote d'Ivoire winger Max Gradel netted the opening goal for the hosts who led 2:1 at the break.
It was Gradel's fourth strike since joining the French side from Leeds United last summer.
Kenya striker Dennis Oliech scored his tenth goal of the season for Auxerre to seal a deserved 2:0 win over Valenciennes.
Before the Harambee Stars skipper's effort in the 66th minute however, Moroccan midfielder Kamel Chafni had given the league's bottom side the lead in the 24th minute.
