But Lampard insisted Giroud was not left out because he was concerned about his mental state after failing to secure a switch, and vowed to offer the France international chances – provided he earns them by working hard in training.
“It was nothing to do with the frame of mind, no,” the 46-year-old coach explained.
“But he has had a few days where a lot of scrutiny has been on him and around him.
“I think it is was case of travelling without him. We will all go away for a week away from each other, it’s probably what’s needed for everyone and we will come back and work hard and Olivier is here.
“If he shows himself in training, because that is how I pick the team generally, then he will get his opportunities.”
French publication RMC Sport have meanwhile claimed that Giroud has been left frustrated with Inter Milan after they failed to follow through with their interest in him.
