Chelsea victory over Barcelona 'doable' - Gary Lineker

BBC presenter and former England striker Gary Lineker says Chelsea's progression to the Champions League final at the expense of Barcelona is "doable".

However, Lineker believes the Blues, who take a 1-0 lead into the second leg of their semi-final, face "an exceptionally gifted side".

He admits preventing the holders from scoring at the Nou Camp is "asking a lot".
