The number nine shirt has been associated with several failed strikers, including Pierre-Emerick Aubameyang, Romelu Lukaku, Gonzalo Higuain, Fernando Torres, and Radamel Falcao. Giroud himself did not wear the number nine shirt during his time at Chelsea, but he was asked about the pressure of playing in that position.

According to Giroud, the pressure of playing striker is not just about the number on your back, but about the demands of the position itself. As a striker, you are under constant scrutiny, both when you are scoring goals and when you are not. You need to be strong mentally and have the confidence to keep working hard, even in tough moments.

Giroud believes that Delap has the talent and quality to handle the pressure of playing striker, and he thinks that the young player will be fine with the help of his teammates. Delap has been included in the squad for the Club World Cup, which starts this weekend.

Giroud's advice to Delap is to focus on his performance on the field and not worry too much about the number on his back. He should be proud to wear the number nine shirt and use it as motivation to work hard and improve his skills.

Overall, Giroud's message to Delap is one of encouragement and support. He believes that the young striker has the potential to succeed at Chelsea, and he is confident that Delap will be able to handle the pressure of playing in the number nine shirt.
