Alan Pardew is trying to rebuild Luuk De Jong’s, confidence, form and fitness, but admitted the Dutch international has to do far more at Newcastle United if he is going to earn a permanent move. De Jong is on loan from German side Borussia Mönchengladbach until the end of the season after a £12.6m move from FC Twente turned sour and is yet to score for Newcastle in eight appearances. The striker was once considered one of the finest prospects in European football, but has arrived in England trying to prove his career has not already imploded at the age of 23. There have been some encouraging signs, but crucially for a centre-forward, De Jong has rarely looked like scoring and, as things stand, there is little chance Newcastle will buy him. “It’s very difficult for a player who has been at a club and not been used after a big money move” said Pardew. “He was a big player, a big personality who scored more goals in Holland than (Wilfried) Bony for example.
