However, on 28 May 2003, after ten years of professional football in Greece he was snapped up by English Premier League side Bolton Wanderers. The manager at the time Sam Allardyce described Stelios as "...an attacking midfielder who knows how to score goals. His main attribute remains his ability to make late runs into the penalty area and his flair to shoot accurately from range." It was at this point that the popular name 'Stelios' came about as the player unconventionally chose for his first name to be printed on his shirt instead of his very long (and difficult for the English journalists) surname. He made his Bolton début against Manchester United and helped Bolton reach the 2004 Football League Cup Final and their highest ever Premier League finish in his first season. Stelios' first two seasons with the club were successful, demonstrated by the fact that both Manchester City and Liverpool openly attempted to sign him before he signed a new contract with Bolton in August 2005.
