The goalkeeper was in fine form to deny the Belgian forward in a 0-0 draw earlier this season, and he has selected that effort as his top save.
Cech has enjoyed a strong start to his Arsenal career since moving from Chelsea over the summer, with it evident that he has already made a big impact on the side.
He was in particularly fine form during the 0-0 draw with Brendan Rodgers’ Reds earlier in the season, as the sides played out an entertaining game at the Emirates despite the lack of goals.
And the Czech keeper his effort to deny Christian Benteke from point blank range was his favourite, explaining why.
“[My favourite was] probably the first one against Benteke because Gabriel tried to intercept the ball when he ran across the goal,” he told arsenal.com.
“Until the last fraction of a second I didn’t know whether he was going to touch it or not. I knew he was running there so I knew that the moment Gabriel missed the ball I had to get there as fast as possible.”
While it is hard to see the influence that Cech has had on the side, he certainly has made a positive impression at the Emirates.
More than anything, the Gunners defence has looked more comfortable with him behind it, with that unit knowing they have a man to make big saves when called upon - such as those in the Liverpool game and the one to deny Manchester United’s Anthony Martial.
Indeed, the decision to drop him for the Champions League loss to Olympiakos further highlighted his importance to the side, and they will be hoping he can produce more big saves with a potential Premier League title challenge on the cards this season.
