Arsene Wenger says Arsenal looked "clinical and mentally fresh" in their 3-0 victory at Hull City on Sunday.
The Gunners were tested by Steve Bruce's side in the first half but survived a handful of scares and put the game out of Hull's reach with ruthless finishes from Aaron Ramsey and Lukas Podolski.
The Germany international added a third after the break to leave Wenger highly satisfied at the final whistle.
"It is important [to have Aaron Ramsey back] because we looked in a few games a bit toothless away from home"
"The first half was very physical, we had to deal with a lot of crosses," he told Arsenal Player. "Our defenders had a great game, they kept us in the game and we were clinical every time we went into their half.
"We looked like scoring goals. In the second half when we scored the third goal, it became easier and we controlled the game well. It was a great performance.
"I felt so [that the team was fresh], it was more mental. The disappointing result we had at Everton had a big bearing and you could see that in the Wigan game. Once we got through that, against West Ham you could see a different team, today you could see a different team."
Ramsey's return, his thrust from midfield and his willingness to make forward runs beyond the main striker gave Arsenal an extra dimension when they went forward at KC Stadium.
"It is important because we looked in a few games a bit toothless away from home," said Wenger. "To have that back is of course a threat for our opponent and it gives us opportunities to score goals."
