Career
He played in The Football League for four clubs during the 1980s. Zelem began with Blackpool on schoolboy forms but was released and joined Chester as an apprentice. His first goal arrived on the opening day of the following season against Bristol Rovers and he became a regular over the next few years.
By the start of 1984-1985 he was the longest serving player at Chester, but he moved midway through the season to Wolverhampton Wanderers for £12,500.
Although this initially gave Zelem the chance to play in the Second Division, the club were rapidly sliding downwards and were in the Fourth Division by the time he linked up with former Chester manager John McGrath at in March 1987. He had the distinction of scoring the first goal in the Fourth Division for Wolves, on 23 August 1986, in their 2–1 home defeat to Cambridge United on the opening day of the league season.
He helped Preston to promotion before joining Burnley in the summer of 1987. After an injury hit two years at Turf Moor, Zelem left the club and joined non-league side Winsford United.
He then moved on to Ashton United, but injury forced him to retire from playing.
Zelem was the first post-war Football League player to have a surname beginning with a Z, first appearing the season before Romeo Zondervan joined Ipswich Town.
