Western Sydney Wanderers are set to make a move to sign exciting Dutch midfielder Roly Bonevacia next season with the Wellington Phoenix midfielder on the cusp of leaving the club when his contract expires on May 31.

Sources suggest the Wanderers are leading a host of A-League clubs in pursuit of the talented playmaker who is unlikely to renew his deal with the Phoenix.

After spending three seasons in Wellington, the former NAC Breda, Roda JC and Ajax man is entertaining a move to a larger club having attracted interest from rival A-League clubs as well as abroad.

It's understood a move back to The Netherlands is unlikely for the 25-year-old, though offers have arrived from other European leagues that could rival bids from within the A-League.
