Liverpool boss Jurgen Klopp is open to further additions to his squad.
Liverpool continue their pre-season preparations against FA Cup winners Arsenal in the Community Shield on Saturday (16:30 BST), and Klopp says he is "happy" with his squad.
However, while remaining coy on the subject, he did not rule out further transfer activity before the Premier League window closes on 5 October.
"Numbers in the squad make sense, we have a big squad at the moment with a lot of young boys, and the size of the squad is OK," he said.
"I'm happy with what we have but we look constantly for improvement - internally too.
"It will be interesting to see what other teams do but we will deal with our situation as we always have. The philosophy of this club is clear and we will see how much we want to spend."
