Lucas Leiva has become the latest in a long line of Liverpool players to be burgled while on the pitch.
The Daily Mail says raiders struck at the Brazil international's home in Woolton while he was playing at Anfield against Atletico Madrid in the Champions League on Tuesday night.
The 21-year-old returned home to find raiders had stolen an Olympic bronze medal he won in the summer as well as a collection of Brazil and Liverpool shirts.
Acting Detective Chief Inspector Peter Parry said: "I would like to empathise to Mr Leiva and his partner for what must have been an upsetting experience.
"As with every burglary victim, we will be carrying out a thorough investigation and offering them crime prevention advice.
"Taken from the address was an amount of jewellery and some very distinctive football and sports memorabilia.
"These items have significant personal importance to Mr Leiva and they were associated with some very cherished memories. I'd ask members of the public to be on the look out in case they are offered such items for sale either on the street or in pubs or see the items for sale on the internet."
