The Hammers victory, under caretaker boss Freddie Ljungberg, was also unconvincing, coming against another struggling side.

Nevertheless, Guardiola – with his own side having surprisingly lost four times this term – is taking nothing for granted.

The former Barcelona boss said: "I have not watched the previous games with Unai, I watched the games they played with Ljungberg to try to figure out what they'll try to do.

"But normally Arsenal have a typical style of play. If you let them play, they have the quality to play. Arsenal away is always a big test for any team."

Ljungberg is a fans' favourite at Arsenal having been a member of the club's 2004 'Invincibles' side and has lifted the atmosphere in the past four games. Emery's reign had ended in dismal fashion after a run of seven games without a win.

Guardiola said: "It was a position after the Unai Emery situation, the club decided on him, of course a person who has had many years at the club.

"He knows the feelings of the club and the fans, the way they like to play. He made a good result the last weekend so we'll see."

Guardiola's highly-rated assistant Mikel Arteta, another former Gunners player, has been linked with the Arsenal vacancy.

Arteta, 37, was also a contender when Arsene Wenger left last year. Guardiola has said he expects Arteta to become a manager one day, and would allow him to leave with his blessing, but only when he feels the time is right.

"You can be 45 years old and believe you are not be ready, or be 35 years old and believe you are ready," Guardiola said. "Only he knows."

City's record goalscorer Sergio Aguero and defender John Stones are still sidelined with thigh and hamstring injuries respectively.

Veteran playmaker David Silva is also a doubt after a blow to the leg in the derby last Saturday.
