Northern Ireland defender Shane Ferguson has signed a five-year deal with Newcastle, the Premier League side confirmed on Friday. Just days after it was revealed that key midfielder Joey Barton will not be offered an extension, the 19-year-old left-back follows Cheick Tiote, Steven Taylor, Mike Williamson and Nile Ranger in putting pen to paper on a long-term deal. \"I\'m really happy. I\'ve enjoyed this season so much and the new contract has just been the icing on the cake for me,\" said Ferguson, who impressed in his nine senior appearances during the second half of last season. \"It\'s a great thrill to play for the club and the support I have had from the fans since making my debut really means a lot so I\'m just delighted to be with Newcastle for the next five years now.\"
