London - Arsene Wenger said that Arsenal had enjoyed a "perfect week" after they won 2-0 at Aston Villa on Sunday to supplant Manchester City at the Premier League summit.
Arsenal reached the Champions League last 16 on Wednesday by winning 3-0 at Olympiakos, Olivier Giroud scoring all three goals, and the Frenchman set the London side on their way at Villa Park with an early penalty.
Aaron Ramsey doubled Arsenal's lead before half-time, starting and finishing a swift counter-attack, as Wenger's men leapfrogged both City and former leaders Leicester City, who host champions Chelsea on Monday.
"It was a perfect week for us," Wenger told the BBC. "We spent a lot of energy away in the Champions League on Wednesday, but found the resources to win again here today (Sunday), in another away match.
"In the first half we were in control, but in the second half the legs had gone a bit. We were mature, and maybe a bit lucky on one or two occasions, but overall it is great to come here and to win away again.
"This season is so unpredictable that you just focus on yourself and try to play well in the next game. You know if you are consistent then you have a chance. This is an opportunity for us to find that consistency."
