Coventry City have signed Danny Philliskirk after successful trial... Coventry City have signed Danny Philliskirk on a contract until the end of the playing season. The 21-year-old forward is a free agent and had been on trial with the Sky Blues for a short period in January. City manager Mark Robins said: “Danny has been with Sheffield United for a couple of years and, prior to that had been acquired by Chelsea. “This fits into our policy of trying to develop younger players who can step through to the first team. We will assess the situation at the end of the season, while giving Danny the opportunity to earn himself a longer term contract.” Philliskirk began his career with Oldham Athletic before being snapped up by Chelsea as a teenager and went on to skipper the club’s youth team. He spent spells on loan with Oxford United and Sheffield United before joining the Blades permanently in 2011.
