Sydney FC are likely to sign Swiss defender Stephan Keller from Dutch club De Graafschap. The 30-year old impressed in a1-1 trial with Newcastle Jets yesterday and Sky Blues coach Vitezslav Lavicka was positive about the prospects of adding him to his playing list.

"I think so," Lavicka said when asked if he would sign Keller. "He is a very good professional, a top player. You could see the experience he brought to the team yesterday."
