Chelsea cannot stop Lionel Messi in the second leg of their Champions League Round of 16 tie at Camp Nou, according to former Spain international Gaizka Mendieta.
The Blues turned in an excellent defensive performance at Stamford Bridge, taking a 1-0 lead through Willian's superb finish.
However, a defensive lapse in the second half allowed Messi the chance to shoot and inevitably score, giving Ernesto Valverde's side a priceless away goal.
The result means that Chelsea will have to score in Spain, and attempt to keep a clean sheet, though Mendieta insists that it is impossible to limit the Argentina superstar.
