Despite an outbreak of coronavirus at the Etihad, Chelsea’s fixture against Man City on Sunday is still expected to go ahead.
Frank Lampard’s side will be desperate to clinch three points at Stamford Bridge, having won just one of their last five matches.
Manchester City have not lost in that period but are two places below Chelsea in the Premier League table ahead of Sunday’s clash.
Belgian playmaker De Bruyne has scored two goals and made seven assists in 13 Premier League appearances this season and Giroud is wary of his threat.
‘Everyone knows the quality of Kevin De Bruyne’s passing at Manchester City but still he is assisting again and again,’ Giroud told Sky Sports.
‘I believe it is one thing to be aware of the quality of the opposition player but to be able to stop it is another thing.’
Giroud has impressed for Chelsea this season, scoring 12 goals in all competitions, and discussed the skills required to be a top-class finisher.
He added: ‘It is something you have or you don’t. A striker can sniff things.
‘I am not going to tell you everything because it will be easy to read me. But it is not all about instinct, it is a skill that he has learned.
‘Being in the right place at the right time is an easy line, but it all comes down to hard work. As a striker, if you want to get free from the defender, you have to make a first run and then after that another run.
‘You feint to go to the far post but end up going to the first post. It is all about that movement to get free from your defender to receive the ball.
‘It is not random. There is nothing random when you score goals. Never. It cannot be that you are just lucky.
‘You are relentless and resilient. You always keep believing. That is one of the main qualities of a striker.
‘You never stop and you always believe that you are going to score even if you miss the first one or the second one.’
