When Hudson McCarthy emailed a video to Chelsea some weeks ago, inviting the team to an authentic Aussie BBQ during their Perth visit, the youngster may not have expected too much.

Yet after finishing their second training session of the day, David Luiz, Tiemoue Bakayoko and Ethan Ampadu drove to the four-year-old’s house across town as a surprise.

Hudson’s parents told him he could stay up past his bedtime as his grandparents were visiting.
