Fabinho's home was burgled as he celebrated Liverpool's long-awaited Premier League win.
Merseyside Police were called to a house in Formby, Sefton, in the early hours of Thursday.
Jewellery and a grey Audi RS6 were stolen, though the car was later recovered in Wigan.
Police think the burglary happened between 3pm on Wednesday and 4am on Thursday. During this time Fabinho had been playing Chelsea at Anfield and celebrating the end of Liverpool's 30-year wait to lift the league trophy.
The players finally got their hands on the one piece of silverware that has eluded the Reds for decades.
Police said the house and car targeted in the burglary have been forensically examined and detectives are collecting security footage from around the area.
