Arsenal boss Mikel Arteta says their new additions have settled quickly.
Kai Havertz, Jurrien Timber and Declan Rice have all arrived this summer.
Arteta said, "We have got some fresh faces in the squad this year, and I am so pleased that we were able to bring these signings in early in the transfer window so we've been able to work with them.
"The feedback we've had from the new players is that they feel like they've been here for years already. That tells you a lot about the culture here, and how welcoming and easy everybody around the place is, to make you feel part of it and part of the Arsenal family straight away.
"Obviously for some of them it has been a big change in the model they're used to, in the demands and expectations, and we have to acknowledge that and treat them in the right way. So let's make sure we give those players some time as well, and to make sure that they have the needed space in which to express themselves, and then get to the level that we want from them. That is always important in helping new players integrate."
