The Germany global joined from Bayer Leverkusen in the summer for £19.3m.
Yet, even with Cech enduring an indifferent start to the season under Emery, the 36-year-old has managed to retain his place. "Sometimes its too easy for a player like that", Glenn Hoddle stated live on BT Sport after the game. "I will work every day hard to play more games". I think that we conceded two goals but not for a mistake [from him].
However, he has been more sedate at the start of the current campaign and has netted just once in the league despite starting the opening five games in the Premier League.
"I came for the Premier League". I think it is the best. Some players are better when they are playing regularly.
One criticism of Cech so far this term is that he has looked uncomfortable with Arsenal's new approach of playing out from the back, something implemented by Emery.
But Leno has always been used to such a style of play and proved that on Thursday, with the German confident his characteristics will suit Emery in the long run.
Head coach Emery made eight changes from the weekend win at Newcastle as goalkeeper Bernd Leno was handed his debut. "I think I did a good job with the ball, with the passing".
The visitors bagged a consolation goal two minutes later as Lichtsteiner went from hero to zero after giving the ball away on the edge of the box, allowing Volodymyr Chesnakov to pounce and fire past Leno. Maybe I need a little bit of time.
"You have to say he's played with a lot of heart, a lot of spirit for a youngster, there's ingredients in his game that might have been missing from the team". "It's clear, we want them to score. Of course, it is very good to work with him and for my development it is very good to have the competition with him".
"We need, because we are going to play a lot of matches in the next weeks, players with confidence", Emery said.
