Though sadly for Blues fans, a number of supporters watching on the club website and app missed out due to technical issues.
Chelsea broke the deadlock in the Florida Cup after their first meaningful attack, with Maatsen, who spent last season on loan at Burnley, finishing off a fine move.
The Dutchman was picked out by summer signing Nicolas Jackson, with the 21-year-old confidently sweeping the ball home past veteran goalkeeper Ben Foster.
However his goal was missed by many supporters, who experienced trouble signing in on Chelsea's website and app, with users left with a '504 gateway time-out' error.
And Twitter users were quick to take to social media to comment on the problem, as one fan said: "Why is the website acting up man I really missed a Maatsen goal."

A third added: "Chelsea can't even get their own website working. Stay up till this time to not even be able to watch the game."
This supporter then messaged: "I never trusted the Chelsea website."
Meanwhile one simply stated: "Chelsea website is awful."
