Age: 19 Position: Defender/Centre Back Nationality: Slovak Lubomir Satka joined Newcastle United in 2012 and has been likened to club captain Fabricio Coloccini. The central-defender is composed, calm and technically very strong and was handed his professional debut against Leicester City in the FA Cup last season. If Newcastle choose not to bring in another defender along with Chancel Mbemba then there is certainly a chance for Satka to compete for a first-team place against the ageing Mike Williamson and Coloccini.
