The Magpies completed the signing of Florian Thauvin this week.
Newcastle have signed the likes of Georginio Wijnaldum, Aleksandar Mitrovic, Chancel Mbemba and Ivan Toney earlier this summer.
“I’m very pleased with what we have got, very pleased,” said McClaren. “I think that’s it for now – but how many times have you heard, ‘That’s it for now’ with 10 days to go of the window?
“We are not expecting, we are not chasing anything. We are not trying to make things happen. Usually with 10 days to go, things might happen.
“But at the moment, we are delighted with what we have got and let’s get to work with them. That’s the key thing now: they’re in, let’s get them working and let’s get them playing.”
