1. Diego Carlos - 4/5

2. Philippe Coutinho - 1/5
The Brazilian seems to be Aston Villa bound and although there was possibly interest from Newcastle, it appears that Coutinho had very little interest in moving to Tyneside.

3. Anthony Martial - 3/5
Early in the window, Sevilla appeared to be Martial’s preferred destination, however, their interest has seemingly cooled - Newcastle may feel a loan move can be achieved.

4. Todd Cantwell - 4/5
There is certainly interest in the Norwich player, Dean Smith has admitted as much. Will Newcastle’s interest transform into a firm offer? Only time will tell.
