13. Samuel Umtiti - 1/5
The noise surrounding Umtiti’s proposed move to Newcastle likely came from Spain as Barcelona remain desperate to offload players. Despite Umtiti barely featuring for Barca this season, he has committed himself to the Camp Nou. Photo: David Ramos
14. Sven Botman - 5/5
After seeing their first bid rejected by Lille, Newcastle have made an improved offer for the defender who is keen on a move to the Premier League. Whether a reluctant Lille will be tempted to sell is another question. Photo: JEAN-CHRISTOPHE VERHAEGEN
15. Dusan Vlahovic - 1/5
Why not get carried away with this one? One of Europe’s most fearsome strikers ending up at St James’s Park? It’s the stuff of dreams - and that’s probably how it will stay this month. Photo: Giuseppe Cottini
