5. Liam Gibson
https://twitter.com/NUFC/status/695972558185852928 The final member of the youth trio to be named on the substitutes' bench against Tony Pulis' men, the 19-year-old full back who models his game on Jordi Alba could be the right man to fill in in the problematic left-back spot. With nine appearances for the Under 21s this season, the youngster has managed to get on the scoresheet once and is winning rave reviews from within the youth team setup. Standing over 6ft-tall, Gibson also offers an aerial presence in both boxes, which is something the Magpies have sorely lacked this term.
