The incident happened at James’ home while he was playing against Zenit Saint Petersburg in the Champions League at Stamford Bridge on Tuesday.
James played the full 90 minutes when Chelsea beat Manchester City 1-0 in the Champions League final last season but was an unused substitute against Villarreal in the Super Cup while his only appearance at the EUROS came in England’s second group stage game against Scotland.
The 21-year-old has taken to social media to share CCTV footage of his home being burgled and has asked for help to retrieve the items.
In a message posted on his Instagram account, James wrote: "On the evening of the 14th of September 2021 when I was playing for my club in the return of the Champions League, a group of cowardly robbers broke into my house.
"They managed to collectively lift a heavy safe containing some personal items of mine into their car. I never keep any jewellery of mine in my house so all that was contained in the safe were my Champions League winners medal and Super Cup winners medal and the runners up medal for the Euro 2020.
"These medals were won representing Chelsea and England - honours that can never be taken away from me whether or not I have the physical medals to prove it.
"Nevertheless, I am appealing to all my Chelsea and England fans to help identify and turn in these low life individuals who will never be able to rest easy as the evidence is mounting against them.
"The police, my advisers and Chelsea FC (and many others) are all behind me as we have firm leads on who the perpetrators are. We are closing in on them.
"Luckily, no one was present during the break in but I want to let all of you know I am safe and well. I really do appreciate having the platform to tell you all about my misfortune and I hope together we can catch these individuals and deliver justice where it is due."
