A leading French based rugby writer believes Israel Dagg, Ben Smith and Aaron Cruden will all leave New Zealand rugby after next year's international season.
The trio are all off contract with New Zealand Rugby next year and are being chased by a number of European clubs.
Rugby journalist Gavin Mortimer told the Radio Sport Breakfast, Dagg is the number one target of big spending Toulon.
