The Blues have a difficult task to defeat the La Liga league leaders , having drawn 1-1 at homeED in the first leg.
Mikel believes Antonio Conte’s men can take inspiration from Chelsea’s 2012 Champions League triumph when they defeated the Catalan club in the semis.
“I have been played [sic] for Chelsea for 11 years and that comeback I will remember for the rest of my life,” Mikel told Tianjin Today Evening News.
“Obviously I will continue to support Chelsea as always and hopefully they will go through into the next round.
“I believe they will knock out Barcelona on their own ground, just like we did in 2012.”
The return leg at Camp Nou is set for March 14.
