The winter window is a notoriously difficult time for sides to try and get transfer business concluded however with clubs often reluctant to lose players midway through the campaign.
One way clubs can avoid this, however, is by signing players on pre-contract agreements. Premier League sides are able to negotiate a pre-contract with players playing outside of the UK from January 1. This pre-contract means players would join on a free transfer once their existing contract expires in the summer.
It is a good way for clubs, like Newcastle, to navigate Financial Fair Play constraints and with the modern game seeing more and more players opting to run down their contracts in order to gain a lucrative move abroad, there are plenty of talented players available for the Magpies to sign on a pre-contract in January.
5. Evan Ndicka
Ndicka played a vital role in helping Eintracht Frankfurt lift the Europa League last season and his name has been mentioned as someone the Magpies may be interested in signing. At just 23 years of age, it is likely that Ndicka still hasn’t reached his potential and could be a key part of any defence for the next decade or so. Photo: Frederic Scheidemann
6. Stefan De Vrij
Much like his teammate Skirinar, the Dutchman has been tipped for a reunion with Antonio Conte at Spurs. At 30, De Vrij is coming to the end of his career, however, it is clear he would still be able to do a job at the highest level if required. Photo: MIGUEL MEDINA
7. Marco Asensio
Asensio has enjoyed a wonderfully successful and trophy laden stint at Real Madrid, however, he may look to move on at the end of his current deal and opt for a new challenge elsewhere in Europe. Photo: Julian Finney
8. Luis Muriel
Muriel has been linked with a move to the Premier League for a number of years now but has yet to make the leap. At 31 he may be just coming down from the peak of his powers however. Photo: Emilio Andreoli
