Formula One champion Sebastian Vettel has sent a stern warning to his championship rivals Lewis Hamilton and Jenson Button that he will be even better this year.
Vettel is looking to complete a hat trick of championship titles this year after being crowned as Formula One champion in 2010 and 2011.
"The idea was to get away in the winter, take time to reflect and hopefully come back stronger, more prepared and more organised," The Sun quoted Vettel, as saying.
He won 11out of 19 races in which he competed last year.
Vettel claimed that he and his team have worked hard on their deficiencies throughout the winter.
"We have sat down as a team and talked through last year and all the things we can improve on. Looking from outside it looked almost perfect but there were quite a lot of things on the list," he added. (ANI)
