Pulisic gunning for first start as ajax storm stamford bridge tonight

I think there may be a few issues with that sentence!

Firstly, Christian Pulisic is an American professional soccer player who plays as a winger for Chelsea FC, not Ajax. Ajax is a Dutch professional football club based in Amsterdam.

Secondly, Stamford Bridge is the home stadium of Chelsea FC, not Ajax. Ajax plays their home matches at the Johan Cruyff Arena in Amsterdam.

So, to correct the sentence:

"Pulisic gunning for first start as Chelsea take on [opponent] at Stamford Bridge tonight."

Let me know if you have any other questions!
