Newcastle boss Eddie Howe admits new signing Sandro Tonali isn't enough.
Howe concedes they've had a frustrating market so far.
"Yeah I think at different times there has been frustrations. "There have been difficult days, because obviously you want the end result, you want the best squad you can get.
"We know the challenges we face. I think the summer we have been through all the emotions.
"We were very pleased to get Sandro through but we know we need more."
