The additions of Sven Botman, Matt Targett and Nick Pope have bolstered the back-line - Newcastle will now turn their attention to strengthening further up the field.
Whether they look to add quality in wide areas or add a striker as competition and cover for Callum Wilson, this is likely to be the next area the Magpies strengthen this window.
Unsurprisingly, a whole host of attacking players have been linked with a move to St James’s Park this summer - but just what would each of them bring to the club should they make the move to Tyneside?

9. Anthony Martial
Martial was heavily-linked with a move to Newcastle in January but opted for a loan move to Sevilla instead. There was seemingly no future for him under previous management at Old Trafford but the Frenchman may be given an opportunity to impress under Erik ten Hag. Photo: MANAN VATSYAYANA
10. Maxwel Cornet
Burnley’s relegation means Cornet is likely to leave Turf Moor this summer. A reported release clause in his contract means a deal shouldn’t be too hard to complete. Photo: LINDSEY PARNABY
11. Jesse Lingard
Lingard remains a free agent after leaving Manchester United. West Ham is seen as the most likely destination for him but the Magpies still hold an interest in the player they were close to signing back in January. Photo: Ash Donelon
12. Nicolas Pepe
Pepe has struggled since moving to Arsenal and may feel a move away from the Gunners is the only way to regain form. PSG are favourites to land the winger but Newcastle have been linked with a move for a while now. Photo: Stuart MacFarlane
