Chelsea scraped past Slavia Prague 1-0 in last week’s Europa League quarter-final first leg at the Sinobo Stadium.
Defender Marcos Alonso was there to head home Willian’s cross in the closing stages of the match.
Spanish goalkeeper Kepa Arrizabalaga pulled off a string of fine saves to deny the gutsy hosts, setting up the Blues to complete the job at Stamford Bridge tonight.
A place in the semi-finals of the Europa League looms but Slavia can still pose a threat to Chelsea.
The Czech league leaders have scored 10 goals in the knockout stages and showed enough quality against Maurizio Sarri’s side to suggest the tie is not over.
Slavia assistant coach Zdenek Houstecky said ahead of the clash: “We fly with hope, we want to advance.
“We’ll do our best for it. I’m sure we’re not giving up. We will play actively and believe that it will work.
“Certainly Chelsea are beatable, so we believe it. Tomas Soucek is our octopus in the middle.”
