Tinkov said in a media release: 'I'm very happy that Alberto will lead Tinkoff-Saxo in 2016 as well, because I truly believe he is the best cyclist in the world and I am convinced he will continue to be so for a few more years. 'Unfortunately, he decided he would retire at the end of next year which means he will race with my team for two full seasons. I would have, obviously, preferred him to stay longer but that was his personal decision. 'However, I am very proud that Alberto's impressive career will conclude in my team and I hope he takes the Tinkoff-Saxo colours to the top step of the Tour de France podium in 2015 and 2016.' Contador added: 'I am very happy to have closed the deal. It is already five years that I have been working with (team manager) Bjarne Riis and the possibility to continue for another year is satisfying.'
