Marko: Red Bull reserve Buemi 'not a winner'

Dr Helmut Marko has dented Sebastien Buemi's hopes of one day moving to Red Bull Racing by insisting the Swiss is not a potential race winner.

Marko, in charge of the energy drink company's driver programme, justified the decision to oust both Buemi and his 21-year-old teammate Jaime Alguersuari from the rookie team Toro Rosso during an interview with La Gazzetta dello Sport.
