Perpignan believe they lost out in the bidding war for Jimmy Gopperth because Newcastle will have an injection of cash in their coffers as a result of the imminent departure of Jonny Wilkinson to Toulon.[LNB] The Falcons announced on Friday the signing of Kiwi fly-half Gopperth on a three-year contract, which is expected to begin when the Air New Zealand Cup finishes at the end of October.[LNB] "I had my doubts about it for the past two or three days," USAP president Paul Goze told French paper L'Independant.[LNB] "With the departure of Wilkinson, the English club raised the bidding. We were no longer on the same wavelength," he added.[LNB] "There was also another problem, regarding the availability of the player.[LNB] "We really wanted him to be here for the start of our season and not at the end of the NPC (National Provincial Championship) in October.[LNB] "By the end of October, we will have almost finished the first half of next season's Top 14."[LNB] Wilkinson is set to seal his switch to Toulon once the French side are mathematically safe from the drop from the Top 14.[LNB] Perpignan, who will bid adieu to New Zealand star Dan Carter next month, will continue their search for a fly-half but Goze confirmed England number 10 Wilkinson was not on his wish-list.
