The Blues take on Leeds United in the Premier League over the weekend.
Giroud started against Sevilla in the Champions League on Wednesday.
He scored four goals in a 4-0 away win, and may have earned himself a spot in the starting lineup for the home Premier League clash on Saturday.
Lampard told BT Sport about Giroud starting against Leeds: "We'll have to see – it's a tight turnaround but it's four goals in a game.
"It's not just his performance but when you play him and utilise his strengths and his speed, there's a real balance in the rest of the team."
