Western Sydney Wanderers have signed Swiss goalkeeper Daniel Lopar in a move that could spell the end for current gloveman Vedran Janjetovic.

Lopar, 34, has penned a one-year deal with the Wanderers from FC St. Gallen, where he has played for the last 13 years, tallying up 299 matches in that time.

He is a familiar face to Western Sydney boss Markus Babbel, who coached FC Luzern in the Swiss league for three years and would have crossed paths with Lopar numerous times.

But it's bad news for Janjetovic, who made several costly mistakes this season and appears to have lost the faith of Babbel. Foreign spots are rarely used on goalkeepers in the A-League, and Babbel would not have signed Lopar if he didn't intend for him to start every match - which means Janjetovic will have to be either content with life as a back-up or look for another club.
