Unai Emery: 'Nacho Monreal back for Chelsea match'

This season, it's Arsenal goalkeeper Petr Cech, who is coming off a rough season for the Gunners and didn't exactly have his best performance in Arsenal's opener, a 2-0 defeat to Manchester City where the Gunners never truly threatened Man City's goal.

Cech started the game despite the recent £22.5 million signing of Bernd Leno, the former Bayer Leverkusen goalkeeper who was reported to have been signed as his replacement. But we needed to play with another player like Ainsley [once Kolasinac was injured]. Leno is just starting with us.

Cech was involved in a Twitter exchange with Leno's former club Bayer Leverkusen on Monday after nearly scoring against City as he attempted a pass across the face of his own goal.

Although Cech indeed has experience in defending Arsenal's goal, he did not do it brilliantly last season, with the north Londoners conceding 51 times in the Premier League - 12 times more than any other team in the top seven and almost double that of Manchester City.

The acquisition of Bernd Leno has effectively ended Ospina's Arsenal career, with the German expected to battle it out with Petr Cech for the No.1 jersey. Also, with Bernd Leno [it's the same].

Emery, however, has been handed a timely boost ahead of only his second Premier League outing.

"We need to keep our personality, keep our mentality", Emery said.

Allardyce claims that the blame lies exclusively with the manager, who he believes sent his team out with the wrong message. Goals from Raheem Sterling and Bernardo Silva ruined Emery's welcome party as his first game as head coach ended with a loss. I want a consistency in our way. "Saturday is a very good option to show our personality, our capacity against a big team like Chelsea, and away from home". "When you win, when you lose, it must be consistent, you must stay regulated, keep thinking positively every day".

"But City made life uncomfortable for Guendouzi at times and I did not feel it was the right game to expose such a young player".
