Chelsea new boy Mykhaylo Mudryk risks the wrath of Arsenal supporters on social media.
The latest Instagram post from Mudryk, who does enjoy being on social media, included himself in a Chelsea shirt.
He also added the caption: "Can't wait to start. Come to do London blue" and a blue heart emoji.
Mudryk had previously been flirting with Arsenal through his Instagram account.
However, the Gunners could not agree a fee with Shakhtar Donetsk, while Chelsea swooped in and secured the deal.
