Petr Cech insists Arsenal are ready to face in-form Manchester United striker Anthony Martial, who has taken the Premier League by storm.
Eyebrows were raised when United forked out a record fee of £36million for a teenager but Martial has silenced the doubters with four goals in his first six matches.
The 19-year-old France international bagged a brace in United's last Premier League away fixture - a 3-2 win at Southampton on September 20.
Arsenal goalkeeper Cech, though, is confident his team-mates are prepared for the teen sensation ahead of Sunday's showdown at the Emirates.
"It's always difficult when you change clubs and come to a big club with a lot of expectation," Cech said via Arsenal's official website.
"Everybody wants to see what you are made of but he had a fantastic start to his United career.
"Maybe the enthusiasm and excitement of moving to the Premier League helps at the start, but then people start expecting things from you and every day they keep reminding you that you are the main goalscorer. It was obviously a dream start for him and we have to make sure that doesn't continue on Sunday.
"We always watch footage of our opponents because the more information you get, the better picture you can have in your head during the game. If there are certain things which keep repeating in the game of any team, then it helps.
"I like to watch the players playing against me to have that idea pre-game - then you can adapt because the game keeps changing every minute.
"It's always good to have an idea of what can happen and the main things that are repeating in your opponents' game. If you want to organise the people in front of you, this information is the main thing for a goalkeeper to have."
