Defiant Contador vows to return stronger

Alberto Contador has protested his innocence over the two-year doping ban imposed by the Court of Arbitration for Sport and insisted he will return to cycling stronger than ever.

The Spaniard has also been stripped of one of his three Tour de France titles for failing a dope test in the 2010 race.

His lawyers are currently considering an appeal, which they must lodge within 30 days.
