A hat-trick from Giroud set the tone as the Blues wrapped up a 5-0 - and 8-0 aggregate - victory over Dynamo Kiev to ease into the Europa League quarter-finals on Thursday. I feel very well physically.
Arkadiusz Milik scored a crucial away goal in the 14th minute to all but end the tie, leaving Salzburg needing five unanswered goals to progress.
"He played very well - better in the second half because we found the spaces and Callum in the spaces is really a very good player", Sarri added.
"I thought he was terrific", Walker said.
"In fact I think he's been very good for Chelsea since he's been at the club, possibly underrated in many respects but proving it again in the Europa League that he can score goals".
"No. No chance. I'm a competitor", Giroud said, per The Sun.
The remaining tie pits Benfica against Eintracht Frankfurt, with the victor facing Chelsea or Slavia Prague in the semi-finals.
Ruben Loftus-Cheek had an excellent game during the week and Sarri was full of praise for the Englishman in his pre-match press conference.
"Chelsea are probably one of the favourites and the performance last night proves why".More news: Tesla changes plans and will keep more stores open
