MILAN (AFP) Team Columbia admit they have no plan B for Milan-SanRemo on Saturday and are counting on sprint king Mark Cavendish to dominate the field if it comes down to it at the end. Cavendish, who won six stages at last years Tour de France, goes into the season-opening one-day classic as defending champion but comparatively under par after a belated start to competition due to dental problems. But if the Isle of Man rider defies his own predictions and manages to endure the suffering he expects on the races two main climbs, the Cipressa and Poggio, he could find himself in with a chance of a rare double. His bosses at Team Columbia admit that having Cavendish in his favoured position of a bunch sprint is their only chance of winning the first of the seasons five 'Monument classics. Milan-San Remo is a very difficult race to predict, there are so many different interests at play and its by no means guaranteed there will be a bunch sprint, said team manager Rolf Aldag. But it could happen, and the team will be working for Mark and supporting him 100 percent. There is no plan 'B. Hes the winner of the 2009 race and hes our best option for winning the race in 2010. Although some rivals, including Italys 2006 champion Filippo Pozzato, have expressed big doubts about Cavendishs form Belgian rival Tom Boonen wont count the Manxman out. Id also have Cavendish in the reckoning although he still must improve a bit, said the Belgian, whose personal favourite is on-form Italian sprinter Daniele Bennati of Liquigas. Katusha rider Pozzato, Fabian Cancellara, the 2008 winner, and emerging Norwegian Edvald Boasson Hagen will spearhead teams hoping to upset the sprinters plans. Team Columbia meanwhile also hope the fact that Cavendish won no stages during an apparently mediocre display at last weeks Tirreno-Adriatico race will take off the pressure. It was a pity it didnt happen but in a way it means less pressure on him, added Aldag. Nobody will be looking at us to chase now if theres a breakaway of 20 riders. However Aldag admitted that if it looks like a lost cause, Cavendish could call off the charge. Marks very clever and very honest and hell let us know exactly whats going on. He wont just kill his team-mates for no reason.
