Club manager, Steve Bruce hopes to clinch the signings of Callum Wilson, Ryan Fraser and Jamal Lewis in the coming days.
Striker Wilson is due at Tyneside after Bournemouth accepted a £20million bid, while winger Fraser arrived on Friday for talks with Bruce. A deal for Norwich City left-back Lewis is also understood to be close.
Bruce – who has lost striker Dwight Gayle for up to four months – is also looking at the loan market, and Arsenal defender Rob Holding is a primary target.
Newcastle’s United’s head coach has also asked Liverpool about the availability of 20-year-old Brewster. Jurgen Klopp, however, could opt to keep Brewster – who spent the second half of last season on loan at Swansea City – at Anfield for now.
