Arsenal defender Laurent Koscielny has said that he has seen the club's two summer signings grow in confidence throughout their pre-season schedule so far.
Sead Kolasinac has featured in all but one of the Gunners' friendlies so far this summer, while Lacazette has played in every game and scored two goals along the way - including one to help his side to the Emirates Cup trophy on Sunday.
Koscielny believes that the new arrivals have settled in well at the club and talked up the progress the team have made during pre-season.
"They have confidence and they're getting more and more during the games. When you are a new player, when you arrive you are quiet, but after [the Emirates Cup] you will have confidence Lacazette and Sead are the same," he told Arsenal Player.
"Sead played well and had more confidence around his teammates, so it's important to keep this up for the club. For Laca, the most important thing is to score. If he scores then he will have the confidence he needs to score a lot of goals.
"We've worked a lot tactically because we're playing with the new system. We had a great pre-season with some good and bad results, but the most important thing is to be ready for the first game.
"We just need to be ready for the first game. We had different players who arrived later than others because of our big squad, so everyone will have a big part to play in our success this season. We just need to be focused with our teammates."
Arsenal's next match comes in the Community Shield against Chelsea on Sunday, before they kick off the new Premier League season at home to Leicester City.
