Attacking dynamo Michael McGlinchey has signed a two-year extension with A-League leaders Central Coast.The 26-year-old New Zealand international linked with the Mariners in 2009 and has since made an impressive 110 appearances for the club.McGlinchey is one of the more influential midfielders in the competition and his consistency had attracted advances from several A-League rivals keen to secure his signature.But McGlinchey, who has been to a World Cup and an Olympics with the All Whites, says the Mariners provided the ideal environment for his development as he agreed to terms until at least the end of the 2014-15 season."It has been going on for a while now and I am just happy to have reached an agreement so that I can stay another two years with the Mariners," McGlinchey said."I think there is good stability at the club, and playing under Arnie (Graham Arnold) is a big factor for me. I've played some of my best stuff under him and I think it is beneficial for me to continue developing here."I came out in 2009 and I think as the years have gone on I've performed better. This is down to the way I have been coached, and I still have a lot of learning to do. The Mariners feel like the best place for me to keep learning."Central Coast coach Arnold expressed his joy that McGlinchey was staying on board."Mikey is an important part of our team for a number of reasons," Arnold said."He can play a number of positions, offers great energy and enthusiasm to the team on the field, and is a great clubman off the pitch."
