The French World Cup winner made only his eighth appearance of the season on Monday night, once again coming off the bench, as Chelsea crashed 2-0 to Manchester United to send the chase for Champions League places wide open.
Giroud said: "I am a Chelsea player. Now I need to move on.
“I want to give everything for the team. My personal target is to play as much as I can so I can play in the Euros. That is massive for me.
“Now I am 100 per cent focused on Chelsea and their targets - I want to keep fighting and get back on the score sheet. Every single game is a big opportunity for me to show my desire to come back."
He added: "After two months without playing I felt very good, with a lot of energy and determination, and I scored a nice goal from a nice cross.
“I tried to stay behind the defender but I was offside by about half a foot. That is very frustrating because it could have changed the game."
