With the Test series against Ireland a mere two weeks away, Springbok coach Allister Coetzee's plans should be at an advanced stage. He will announce his squad for the trio of Tests in Cape Town on Saturday before a training camp for a fortnight in Stellenbosch.Having recently concluded a visit to all six South African Super rugby franchises, Coetzee would have felt as though he had all his ducks in a row. However, the untimely injury to Lions flyhalf Elton Jantjies and the big question mark that remains over Duane Vermeulen's availability for the June Tests, proves that even the best laid plans can go awry.Jantjies has been the form flyhalf in the Super rugby competition and his finger fracture, which could sideline him for up to a month, is what we commonly refer to in professional coaching circles as a thunderbolt. Coetzee would have potentially been hoping to pair Jantjies and Faf de Klerk, but the former's injury setback has thrown a spanner in the works.Jantjies has marshalled the Lions' backline with purpose and panache this season and he has arguably been in the form of his life. If he fails to recover in time to take on the Irish, it will prove a significant blow for South Africa.Patrick Lambie's return from injury, however, is very good news for the Springboks. It represents something of a silver lining for Coetzee as the Sharks captain is getting back to his best and is highly qualified to wear the No10 jersey.The second thunderbolt that could strike the Springboks is the potential unavailability of South Africa's premier No8, Vermeulen, who is rumoured to be earning just under à1-million (R17-million) a year in the south of France.Marquee players are being paid an absurd amount of money abroad, and some people may even go as far as to suggest that Vermeulen sold his soul when he signed for Toulon last year. It's easy to point a finger at the player, but the reality is that at the age of 29 Vermeulen had to secure the future of his young family.Though the top echelon of players in South Africa earn salaries of between R6-million and R10-million a year, the overseas market has skyrocketed in terms of earning potential.If Vermeulen opts to play for the Springboks if selected, he runs the risk of not getting paid by Toulon during that period. Toulon owner Mourad Boudjellal is a tough businessman - he wants a return on his investment - and has threatened to withhold payment from any player who opts to represent his nation in June.As such, Vermeulen finds himself caught between a rock and a hard place. A tug-of-war between Toulon and SA Rugby is set to ensue and, unfortunately, the party that will suffer most is the player himself.If Vermeulen chooses club over country, it has been reported that he must tender his resignation from international rugby in writing, which will rule him out of Tests for a minimum of six months.Coetzee will be desperate for Vermeulen to avail himself for South Africa because, over and above his exploits as a player, the two formed an effective working relationship at domestic level. The coach-captain relationship is an essential part of any team's success...
