The France international completed a £21m move to Chelsea FC from Arsenal in the January transfer window after falling out of favour under Arsene Wenger.
Giroud scored the opening goal in Chelsea FC’s 2-0 win against Southampton at the FA Cup semi-final at Wembley last weekend.
The 31-year-old has netted five and has made three assists since his move to Arsenal’s bitter rivals on transfer deadline day back in January.
Giroud’s former team-mate Sanchez completed a swap deal to Manchester United from Arsenal to end speculation surrounding his future.
The Chile international cancelled out Dele Alli’s opening goal before Ander Herrera netted a second-half goal winner to seal a 2-1 victory over Tottenham Hotspur in the FA Cup semi-final at Wembley.
Speaking to Chelsea FC’s website about coming up against his former team-mate in the FA Cup final at Wembley next month, Giroud said:
“I love to play here [at Wembley]. I was joking before and I said it’s my garden. I want to continue the good luck and success I’ve got here.
“I want to win the FA Cup with Chelsea now. I told my team-mates: ‘Look guys, I’m unbeaten here and I want this momentum to carry on.’
“I know what a great feeling it is to win the FA Cup and I want them to know this too. He [Sanchez] has been unbeaten as well. But he only signed in 2014 for Arsenal. I will be happy to see him. It’s always special to play with old players, especially when we had good memories.”
Chelsea FC are in fifth place in the Premier League table and five points adrift of Tottenham Hotspur, who occupy the final Champions League qualification spot.
