Chelsea winger, Mykhaylo Mudryk, became the fastest player in the Premier League this season during his debut.
The Ukraine international joined the Blues in an £87m move from Shakhtar Donetsk this month.
His first appearance for the club came at Anfield when they played Liverpool.
The 22-year-old came on in place of Lewis Hall in the second half.
Despite having only been on the pitch for just over half an hour, Mudryk broke a Premier League record for the current campaign.
