After his six-month professional contract at Inter Milan came to an end, Greenhalgh was offered another year from the Italian giants which included a four-month loan spell to Calcio Como, where he scored eight goals from 12 games. Despite never playing a senior game during his time with Inter Milan, Greenhalgh was presented with a Champions League Winners medal after being part of the travelling squad for the 2010 UEFA Champions League Final. After his contract was up, he returned to the UK and spent time at Brighton &amp; Hove Albion, as well as a spell at Birmingham City, where he was advised to play first team football in the Conference to gain experience in the English game. He signed for non-League club Welling United in December, before later joining Ebbsfleet United and Maidstone United.
