Arsene Wenger has pinpointed three major issues which his Arsenal side need to address when they face Sutton United in the fifth round of the FA Cup.
The Gunners will have to cope with an artificial playing surface at Gander Green Lane on Monday evening, with National League Sutton hoping to set up an all-non-league meeting with Lincoln City in the last eight of the competition.
Wenger is also wary of the commitment he expects from the Yellows, who knocked out Leeds United in the fourth round, while also warning that his own players have to be mentally up for the challenge.
He told reporters: "(My concerns are) first of all the pitch, secondly their enthusiasm. Thirdly that we are not ready mentally for a big fight and think subconsciously that it doesn't matter.
"Ideally we would like to play on a normal pitch. Competition is as well to deal with what you face and we'll face an unusual pitch and we'll have to deal with it.
"We practiced inside (on Friday) because we have an artificial pitch. It's not the same as it's a dry pitch and at Sutton I've heard that's a wet pitch, they water it before the game.
"So it will be much quicker than what we have."
Wenger has also confirmed that fit-again striker Danny Welbeck will not feature against Sutton, as he does not want to risk the England international on the artificial surface of the non-league outfit.
The Gunners are 10/1 to win 1-0 in normal time at Gander Green Lane, while they are 11/2 to triumph 2-0 and 11/2 to secure a 3-0 victory in 90 minutes.
