The club did not allow the opponent to win the match in both matches.
Arsenal managed to beat Manchester United in both home and away matches earlier in the 2006/07 season, which is why they are missing out in the race for the championship - reports Squawka.
That team won at Old Trafford 1:0 thanks to Emmanuel Adebayor's goal, and in the other match at Emirates they won 2:1 with goals from Robin van Persie and Thierry Henry, which led to Wayne Rooney's accurate strike.
In the match against Manchester United, Mikel Arteti's team won 1:0 thanks to a goal from Leandro Trossard.
Arsenal are currently in first place in the table.
